Question

For the reaction, CaO + 2HCl → CaCl2 + H2O
1.23g of CaO is reacted with excess of HCl and
1.85g of CaCl, is formed. What is percent yield ?​

Answer 1

Answer:

The balanced equation is:

56g

1mol

CaO

+2HCl→

111g

1mol

CaCl

2

+H

2

O

56 g of CaO produce CaCl

2

=111g

1.23 g of CaO produce CaCl

2

=

56

111

×1.23.=2.43g

Thus, Theoretical yield = 2.43 g

Actual yield =1.85 g

Per cent yield =

2.43

1.85

×100=76.1

Hope it helps.
