Answer 1

Hii friend ,

Here is your answer...

According to law of constant composition,the values obtained should be same.

(1) 5.18 g = 6.45 g

x g = 100 g

x= 5.18 ×100/6.45

x =80.3 g

(2) 1.10 =1.37

"x" g = 100g

x =1.10×100/1.37

x = 80.3 g

(1) =(2)

Hence law of constant conposition is verified.

Hope this helps you a little!!
