Answer:

142.0mol CO2

Explanation:

To convert from molecules to moles we must divide the amount of molecules by Avagadro’s number, 6.02 x 10^23.

8.551 x 10^25 / 6.02 x 10^23 = 142.0mol CO2

Answer:

Explanation:

moles= no. of molecules/ avagardo number

        =8.511*10^25/ 6.022*10^23

        =14.13 moles

What is the atomic number of this atom?<br><br> 6<br> 8<br> 9<br> 16
GaryK [48]

The atomic number of this atom : 8

<h3>Further explanation</h3>

Given

Atomic model (attached)

Required

The atomic number

Solution

To determine the atomic number of an element, we can look at the number of electrons or the number of protons, because

atomic number = number of protons = number of electrons in neutral atoms

While the mass number is the number of neutrons + the number of protons located in the atomic nucleus

The charge of each of these atomic sub particles:

  • electron: charge -1
  • proton: charge +1
  • neutron: not charged / 0

If we look at this atomic model, there are 8 electrons in the shell, consisting of 2 electrons in the first shell and 6 electrons in the second shell (which can also be called valence electrons)

Whereas in the atomic nucleus there are 8 protons and 10 neutrons

xxTIMURxx [149]
Mass spectrometry was discovered by Francis Aston, a British Physicist, in 1919. This involves separating mixtures of substances into their components and transforming them into beams of particles and subsequently, bending them with the use of electricity and magnetism to come up with a spectrum that is inherently unique for every individual atoms for easy identification.
