The volume occupied by one gram of oxygen gas:
Correct answer: B. 0.70 dm3
- A. 22.414 dm3
- B. 0.70 dm3
- C. 22414 cm3
- D. 0.22414 m3
Explanation
Number of moles=mass/molar mass=1/32= 0.0312 moles. Use ideal gas law: PV=nRT. V=nRT/P. V=(0.03125mol)(0.0821L.atm/mol.K)(273.15K)/1atm V= 0.697L/dm3 So option B is correct.

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.
