Answer:

The answer to your question is 62.16 g of CaO

Step-by-step explanation:

Data

mass = ?

moles = 1.11 of CaO

molecular mass of CaO = 40 + 16 = 56 g

Process

1.- Use proportions and cross multiplication to solve this problem

56 g of CaO ------------------- 1 mol of CaO

x g of CaO ------------------- 1.11 moles of CaO

x = (1.11 x 56) / 1

2.- Simplification

mass of CaO = 1.11 x 56

= 62.16 g
