In volumetric analysis, how does one convert concentration from g/dm3 to mol/dm3?

Chemistry
1 answer:
Cloud [144]3 years ago

gdm^-3/gmol^-1

g/g=1  dm^-3/1=dm^3    1/mol^-1=mol^1      1 x dm^-3 x mol^1     mol/dm^3

To convert from g/dm^3 to mol/dm^3 you have to divide g/dm^3 by g/mol or the molecular mass.

The product of a Lewis acid-base reaction is a(n) __________, a single species that contains a new covalent bond. The Lewis acid
andreyandreev [35.5K]

Answer:

Adduct, donate, accept

Explanation:

Lewis acids are those having suitable vacant orbital for electron acceptance and forming a covalent bond with an electron rich species. Example: BCl_{3} (B has vacant 2p orbital for electron acceptance)

Lewis bases are those having energetically available unshared electrons that can be donated to an electron deficient species and form a covalent bond. Example: NH_{3} (N has energetically available lone pair)

So, product of Lewis acid-base reaction is an adduct (BCl_{3}-NH_{3}) where a new covalent bond is formed between B and N.

The specific heat of water is 4.18 J/(g⋅∘<br> c. Calculate the molar heat capacity of water.
Xelga [282]

We are given that the specific heat of water is 4.18 J / g °C. We know that the molar mass of water is 18.02 g/mol, therefore the molar heat capacity is:

 

molar heat capacity = (4.18 J / g °C) * 18.02 g / mol

<span>molar heat capacity = 75.32 J / mol °C</span>

An upward force acts on a proton as it moves with a speed of 2.0 × 105 meters/second through a magnetic field of 8.5 × 10-2 tesl
mel-nik [20]

Explanation :

It is given that,

Speed of the proton, v=2\times 10^{5}\ m/s

Magnetic field, B=8.5\times 10^{-2}\ T

Magnetic force is given by :

F=q(v\times B)

q is the charge of proton, q=1.6\times 10^{-19}\ C

So,

F=1.6\times 10^{-19}\ C\times 2\times 10^{5}\ m/s\times 8.5\times 10^{-2}\ T

F=2.72\times 10^{-15}\ N

The direction of force is given by using right hand rule. So, the force will act in upward direction.

Hence, the correct option is (a) " 2.72\times 10^{-15}\ N to the north".
