Question

Na2S04 XH2O has 50% H2O Hence, is
(A) 4
B) 5
C) 6
D) 8​

Answer 1

Answer:

option C is correct ans

Answer 2

Answer:

Molar mass of Na2So4 is

2.23 +32 + 4.16 = 142

Molar mass of H2O = 2.1 +16=18

So, 18X/142 = 0.5/0.5= 1

Or, X = (142/18) = 8 ( proved)...i hope it helps you

The answer would be = D) 8

Hope it will help you....
