0.986 moles of CaO are formed when 98.60 g of [tex]CaCO_3[/tex]decomposes.
A mole is defined as 6.02214076 ×[tex]10^{23}[/tex] of some chemical unit, be it atoms, molecules, ions, or others.
Number of moles of CaCO3 =[tex]\frac{mass}{molar \;mass}[/tex]
Number of moles of CaCO3 = [tex]\frac{98.60 g}{100 g/mol}[/tex]
= 0.986 moles
Reaction:
[tex]CaCO_3[/tex] → [tex]CaO + CO_2[/tex]
Since the reaction is 1:1:1.
So 0.986 moles of CaO are formed.
