Answer:
132g
Explanation:
The reaction equation is given as:
CaCO₃ → CaO + CO₂
Given;
Number of moles of CaCO₃ = 3 moles
Unknown:
Mass of CO₂ produced = ?
Solution:
From the balanced reaction equation;
1 mole of CaCO₃ will produce 1 mole of CO₂;
3 mole of CaCO₃ will then produce 3 moles of CO₂
To find the mass of CO₂;
Mass of CO₂ = number of moles x molar mass
Molar mass of CO₂ = 12 + 2(16) = 44g/mol
Mass of CO₂ = 3 x 44 = 132g
