Practice Questions

Under standard conditions, one mole of an ideal gas occupies

A. 11.2 L
B. 22.4 L
C. 44.8 L
D. 24.0 L

At STP (0°C and 1 atm), one mole of any ideal gas occupies 22.4 L. Values like 24.0 L apply approximately at room temperature, not STP. Concept tested: Molar volume of gases.

During the combustion reaction CH₄ + 2O₂ → CO₂ + 2H₂O, complete combustion of 3 moles of methane produces

A. 2 moles of CO₂
B. 3 moles of CO₂
C. 4 moles of CO₂
D. 6 moles of CO₂

The balanced equation shows a 1 : 1 mole ratio between CH₄ and CO₂. Thus, 3 moles of methane produce 3 moles of carbon dioxide. Concept tested: Mole ratio application.
