Question

What is the correct mathematical relationship between the number of moles, the volume, and the standard molar volume of a substance?

Answer 1

`V_(m) = (V)/(n)`

Step-by-step explanation:

Molar volume is the volume occupied by 1 mole of a substance.

For gases, based on the ideal gas law we have:

`PV = nRT`

where, P = pressure, V= volume, n = moles, R = gas constant, T = temperature

`(V)/(n) = (RT)/(P)`

Here, the molar volume is given as:

`V_(m) = (V)/(n)`

Under standard temperature and pressure conditions, the molar volume of an ideal gas is 22.4 L/mol

Answer 2

The relationship is:
standard molar volume = volume / moles
