61.8g of A combines with 80g of B.30.9g of A combines with 106.5g of C, B and C combine to form compound CB2.atomic weight of C and B are respectively 35.5 and 66.6.show that the law of reciprocal proportion is obeyed

Answer 1

Answer:

Explanation:

Given  

61.8 g of A combines with 80 g of B.30.9 g of A combines with 106.5 g of C, B and C combine to form compound CB2. atomic weight of C and B are

Now we know that when two different elements combine separately with a fixed mass of a third element, the proportion they combine with one another will be either in same ratio or some multiple of it.

Ratio of mass of A and B = 61.8 : 80 = 30.9 : 40

Ratio of mass of C and B2 = 35.5 : 2 x 6.6 = 35.5 : 13.2

Ratio of mass of A and C = 30.9 : 106.5

Now according to ratio of masses of  C and B is 106.5 : 40 which is equal to 35.5 : 13.2.

So law of reciprocal proportion holds good.
