Answer 1

Explanation:

ANSWER

Mass of copper in copper chloride =1.89 g (given)  

Mass of Chlorine in Copper Chloride =2.11 g

% age of Cu in 4 g of copper chloride =  

4

1.89

​  

×100=47.25%

% age of Cl in 4 g of copper chloride =  

4

2.11

​  

×100=52.75%

∴ In 100 g of sample:  

Mass of Cu=47.25 g

Mass of Cl=52.75 g

Moles of Cu=  

63.5

47.25

​  

=0.74

Moles of Cl=  

35.5

52.75

​  

=1.48

So, ratio of moles of Cu and Cl =  

1.48

0.74

​  

=  

2

1

​  

 

Thus, the empirical formula of the compound is CuCl
