Which one is the molar volume of the gas at STP?
Correct answer: B. 22.4 dm3
- A. 24 dm3
- B. 22.4 dm3
- C. 80 dm3
- D. 40 dm3
Explanation
At standard Temperature and Pressure (STP) the molar volume (Vm) is the volume occupied by one mole of a chemical element or a chemical compound. It can be calculated by dividing the molar mass (M) by mass density (ρ). Molar gas volume is one mole of any gas at a specific temperature and pressure has a fixed volume. 1 mole of any gas occupies 22.4 dm3 volume at STP.

About Fundamental Concepts of Chemistry
Mole calculations connect mass, number of particles and Avogadro's number, while balanced equations provide the mole ratios used in stoichiometry. Questions cover limiting and excess reactants, theoretical yield and percentage yield, including identifying which reactant is consumed first and comparing the actual product with the maximum possible product.
