1 Atomic mass unit is the mass of an atom or it caliberates mass on atomic scale. It is also expressed in dalton denoted by Da whereas Atomic mass unit is denoted by amu.

1 amu can be expressed in grams as follows:

1 amu = 1.6 * 10^-2^4 g

Mass of Te = 127.6 amu

For converting in grams,

M = (127.6 ) * 1.6 * 10^-2^4 g

M = 204.16 * 10^-2^4 g

Thus, mass of Te is 204.16 * 10^-2^4 g

The mass, in grams, of a single tellurium atom = 2,118. 10⁻²² grams

<h3>Further explanation</h3>

Inside the atom consists of a nucleus containing 3 elementary particles, namely protons and neutrons, while electrons move around the nucleus.

Protons are positively charged (+1), electrons are negatively charged (-1). and neutrons are uncharged (neutral)

While the mass of 1 proton is equal to the mass of 1 neutron, equal to 1 amu and the electron has a mass smaller than both.

Atomic mass is the average atomic mass of all its isotopes

In determining the mass of an atom, as a standard is the mass of 1 carbon-12 atom whose mass is 12 amu

So the atomic mass obtained is the mass of the atom relative to the 12th carbon atom

An atomic mass unit = amu is a relative atomic mass of 1/12 the mass of an atom of carbon-12.

The 'amu' unit has now been replaced with a unit of 'u' only

The hydrogen atom is the lightest atom whose mass is 1.67 x 10⁻²⁷kg (measured using a mass spectrometer) and simplified to 1 amu (atomic mass unit).

1 amu = 1,66.10⁻²⁴ grams

For example the C-12 carbon atomic mass is 12 amu, C-13 is 13 amu

Single tellurium atoms have = 127.60 amu

So that the mass is in grams:

mass = 127.60 amu x 1.66.10⁻²⁴

mass = 2,118. 10⁻²² grams

Based in the rules of John Dalton, what is a possible hypothesis that could be tested in the Atomic Theory lab?
marshall27 [118]
<span>After many experiments and many different approaches to the question, the scientist may be able to develop a theory. The theory explains why nature behaves in the way described by the natural law. It answers not only the original question, but also any other questions that were raised during the process. The theory also predicts the results of further experiments, which is how it is checked. Theories are not the end of the process.</span>

A solution of sodium hydroxide (NaOH) was standardized against potassium hydrogen phthalate (KHP). A known mass of KHP was titra
Eddi Din [679]

Answer:

See explanation below

Explanation:

In order to calculate this, we need to use the following expression to get the concentration of the base:

MaVa = MbVb (1)

We already know the volume of NaOH used which is 13.4473 mL. We do not have the concentration of KHP, but we can use the moles. We have the mass of KHP which is 0.5053 g and the molecular formula. Let's calculate the molecular mass of KHP:

Atomic weights of the elements to be used:

K = 39.0983 g/mol;  H = 1.0078 g/mol;  C = 12.0107 g/mol;  O = 15.999 g/mol

MM KHP = (1.0078*5) + (39.0983) + (8*12.0107) + (4*15.999) = 204.2189 g/mol

Now, let's calculate the mole of KHP:

moles = 0.5053 / 204.2189 = 0.00247 moles

With the moles, we also know that:

n = M*V (2)

Replacing in (1):

n = MbVb

Now, solving for Mb:

Mb = n/Vb  (3)

Finally, replacing the data:

Mb = 0.00247 / (13.4473/1000)

Mb = 0.184 M

This would be the concentration of NaOH

What are the characteristics of the two systems of government in this region? Explain in detail.
Anna11 [10]

Answer:

space agency of the Republic of India, headquartered in Bengaluru. It operates under Department of Space (DoS) which is directly overseen by the prime minister of India while chairman of ISRO acts as executive of DoS as well. ISRO is the primary agency in India to perform tasks related to space based applications, space exploration and development of related technologies.[6] It is one of six government space agencies in the world which possess full launch capabilities, deploy cryogenic engines, launch extraterrestrial missions and operate large fleets of artificial satellites.[7][b]

The Indian National Committee for Space Research (INCOSPAR) was established by Jawaharlal Nehru[8] under the Department of Atomic Energy (DAE) in 1962, with the urging of scientist Vikram Sarabhai recognising the need in space research. INCOSPAR grew and became ISRO in 1969,[9] also under the DAE.[10][11] In 1972, the Government of India had set up a Space Commission and the Department of Space (DOS),[12] bringing ISRO under the DOS. The establishment of ISRO thus institutionalised space research activities in India.[13] It is managed by the DOS, which reports to the Prime Minister of India.[14]

ISRO built India's first satellite, Aryabhata, which was launched by the Soviet Union on 19 April 1975.[15] It was named after the mathematician Aryabhata. In 1980, Rohini became the first satellite to be placed in orbit by an Indian-made launch vehicle, SLV-3. ISRO subsequently developed two other rockets: the Polar Satellite Launch Vehicle (PSLV) for launching satellites into polar orbits and the Geosynchronous Satellite Launch Vehicle (GSLV) for placing satellites into geostationary orbits. These rockets have launched numerous communications satellites and Earth observation satellites. Satellite navigation systems like GAGAN and IRNSS have been deployed. In January 2014, ISRO used an indigenous cryogenic engine CE-7.5 in a GSLV-D5 launch of the GSAT-14.[16][17]

ISRO sent a lunar orbiter, Chandrayaan-1, on 22 October 2008, which discovered lunar water in the form of ice,[18] and the Mars Orbiter Mission, on 5 November 2013, which entered Mars orbit on 24 September 2014, making India the first nation to succeed on its maiden attempt to Mars, as well as the first space agency in Asia to reach Mars orbit.[19] On 18 June 2016, ISRO launched twenty satellites in a single vehicle,[20] and on 15 February 2017, ISRO launched one hundred and four satellites in a single rocket (PSLV-C37), a world record.[21][22] ISRO launched its heaviest rocket, Geosynchronous Satellite Launch Vehicle-Mark III (GSLV-Mk III), on 5 June 2017 and placed a communications satellite GSAT-19 in orbit. With this launch, ISRO became capable of launching 4-tonne heavy satellites into GTO. On 22 July 2019, ISRO launched its second lunar mission Chandrayaan-2 to study the lunar geology and the distribution of lunar water.

Future plans include development of the Unified Launch Vehicle, Small Satellite Launch Vehicle, development of a reusable launch vehicle, human spaceflight, a space station, interplanetary probes, and a solar spacecraft mission.
