Answer:
5.22 moles of Na₂CO₃ have mass of 553.22 g
Explanation:
Given data:
Mass of Na₂CO₃ = ?
Number of moles of Na₂CO₃ = 5.22 mol
Solution:
Formula:
Mass = number of moles × molar mass
Molar mass of Na₂CO₃ = 105.98 g/mol
Mass = 5.22 mol × 105.98 g/mol
Mass = 553.22 g
Thus, 5.22 moles of Na₂CO₃ have mass of 553.22 g.
