german

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.
