The volume occupied by 4.4g of CO2 at STP is?
Correct answer: A. 2.24 dm3
- A. 2.24 dm3
- B. 112 cm3
- C. 22.4 dm3
- D. 1.12 dm3
Explanation
At STP (Standard Temperature and Pressure), 1 mole of any gas occupies 22.4 dm3. The molar mass of CO2 is 44g/mol. Therefore, the number of moles in 4.4g of CO2 is 4.4g / 44g/mol = 0.1 moles. The volume occupied by 0.1 moles of CO2 is 0.1 x 22.4 dm3 = 2.24 dm3.The other options are incorrect because they either underestimate or overestimate the volume based on incorrect calculations or misconceptions about molar volume.

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.
