Question: If 2 moles of a gas occupy 44.8 L at STP, what is the molar volume of the gas?

Options:

Correct Answer: 22.4 L

Solution:

At STP, 1 mole of gas occupies 22.4 L. Therefore, the molar volume of the gas is 22.4 L.

If 2 moles of a gas occupy 44.8 L at STP, what is the molar volume of the gas?

If 2 moles of a gas occupy 44.8 L at STP, what is the molar volume of the gas?

Step 1: Understand that STP stands for Standard Temperature and Pressure.
Step 2: Know that at STP, 1 mole of any ideal gas occupies 22.4 liters.
Step 3: Since we have 2 moles of gas, we can confirm that they occupy 44.8 liters (2 moles x 22.4 L/mole = 44.8 L).
Step 4: The question asks for the molar volume of the gas, which is the volume occupied by 1 mole of gas.
Step 5: Since we already know that at STP, 1 mole of gas occupies 22.4 liters, we conclude that the molar volume of the gas is 22.4 L.

Molar Volume at STP – At standard temperature and pressure (STP), one mole of an ideal gas occupies 22.4 liters.
