0.986 moles of CaO are formed when  98.60 g of CaCO_3decomposes.

<h3>What are moles?</h3>

A mole is defined as 6.02214076 ×10^{23} of some chemical unit, be it atoms, molecules, ions, or others.

Number of moles of CaCO3 =\frac{mass}{molar \;mass}

Number of moles of CaCO3 = \frac{98.60 g}{100 g/mol}

= 0.986 moles

Reaction:

CaCO_3   →  CaO + CO_2

Since the reaction is 1:1:1.

So 0.986 moles of CaO are formed.

VMariaS [17]

The solution is 45.7 % (NH₄)₂CO₃ by mass.

Mass of solution = 0.0332 kg + 0.0395 kg = 0.0727 kg

% (NH₄)₂CO₃ = Mass of (NH₄)₂CO₃/Total mass × 100 % = 0.0332 kg/0.0727 kg × 100 % = 45.7 %
