What is an example of a molar volumes of gases practice problem?

Question

Peyton Adams · Accepted Answer

Under standard conditions, a gas occupies #29*L#; what is the molar quantity of the gas?

Of course, the question will specify the standard conditions, and also quote the molar volume of a gas under same conditions. Typically, under standard conditions of #1*"bar"# and #298*K#, such volume is #24.8*dm^3*mol^-1#... ...and here #1*dm^3#, a unit of VOLUME is... #1*dm^3-=(1xx10^-1*m)^3=10^-3*m^3-=1*L#... i.e. #1*L-=1*dm^3#... If you want more such examples, perhaps you should specify at which level you study...

undefined An example of a molar volume of gases practice problem could be:

Calculate the molar volume of hydrogen gas at STP (Standard Temperature and Pressure), where STP is defined as 0°C (273 K) and 1 atmosphere of pressure.

Solution:
Given:
Temperature (T) = 0°C = 273 K
Pressure (P) = 1 atmosphere (atm)
Molar mass of hydrogen (H2) = 2.016 g/mol

Using the ideal gas law equation:
PV = nRT

We rearrange the equation to solve for volume (V):
V = (nRT) / P

Since we're solving for molar volume, we'll use one mole of hydrogen gas (n = 1 mole).

R is the ideal gas constant, which is 0.0821 L atm / K mol.

Substituting the values:
V = (1 mole * 0.0821 L atm / K mol * 273 K) / 1 atm
V ≈ 22.4 L

Therefore, the molar volume of hydrogen gas at STP is approximately 22.4 liters.
