Question
A certain sample contains 4.86 moles of calcium carbonate. What is the mass of calcium carbonate [Ca = 40, C = 12, O = 16]?
Correct Answer
Option C is the correct answer.
Detailed Explanation
Molar mass CaCO₃ = 40+12+(3×16)=100 g/mol. Mass = 4.86 mol × 100 g/mol = 486 g.
Hint
Mass = moles × molar mass.
