Question: If 3 moles of a gas occupy 60 liters at STP, what is the molar volume of the gas?

Options:

Correct Answer: 30 L

Solution:

Molar volume = total volume / number of moles = 60 L / 3 moles = 20 L/mole.

If 3 moles of a gas occupy 60 liters at STP, what is the molar volume of the gas?

If 3 moles of a gas occupy 60 liters at STP, what is the molar volume of the gas?

Step 1: Understand that molar volume is the volume occupied by one mole of a gas.
Step 2: Identify the total volume of the gas, which is given as 60 liters.
Step 3: Identify the number of moles of the gas, which is given as 3 moles.
Step 4: Use the formula for molar volume: Molar volume = total volume / number of moles.
Step 5: Substitute the values into the formula: Molar volume = 60 liters / 3 moles.
Step 6: Calculate the result: 60 liters divided by 3 moles equals 20 liters per mole.

Molar Volume – Molar volume is the volume occupied by one mole of a substance at a given temperature and pressure, typically measured at STP (Standard Temperature and Pressure).
STP Conditions – STP refers to standard temperature (0°C or 273.15 K) and standard pressure (1 atm), which are the conditions under which the molar volume of an ideal gas is usually defined.
