KIM [24]

Answer:

0.014mol

Explanation:

Given parameters:

Mass of Na₂CO₃ = 1.5g

Unknown:

Number of moles = ?

Solution:

Number of moles of a compound is mathematically expressed as;

Number of moles = $\frac{mass}{molar mass}$

Molar mass of Na₂CO₃ = 2(23) + 12 + 3(16) = 106g/mol

Number of moles = $\frac{1.5}{106}$ = 0.014mol
