Question

find the no.of miles of crystallization I need correct answer...​ If you answer me then I will mark you as BRAINLIST and try to follow you...

Answer 1

Answer:

The formula of the salt will be MSO

4

.nH

2

O

Molar mass of the salt will be = 65.4+32+4×16 + n×18 = 161.4+18 n

On dehyration, all H

2

O molecules will evaporate and the formula of the salt becomes MSO

4

having molar mass 161.4

Therefore, we can say that

35.85% of (161.4+18n) = 161.4

or, 35.85100×(161.4+18n)=161.4

or, 161.4+18n =

35.85

161.4×100

or, 161.4+18n = 450.20

or 18 n = 450.20−161.4 = 288.80or, n =

18

288.80

= 16

Hence, the number of molecules of water of crystallisation = 16
