20 gram monoatomic gas occupies 44.8 dm³ at STP what is the atomic mass weight of gas
Correct answer: B. 10g
- A. 5g
- B. 10g
- C. 20g
- D. 40g
Explanation
One mole of the monoatomic gas have weight equal to atomic mass of the gas hence xg => 22.414dm320g => 44.8dm3x=10g.

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.
