Hydrogen and its compoundHard
Question
26.8 gm of Na2SO4.nH2O contains 12.6 gm of water. The value of ′n′ is ?
Options
A.1
B.10
C.6
D.7
Solution
Na2SO4.nH2O
Molar mass = (142 + 18n)
Mass of water =
× (142 + 18n)
18n =
× (142 + 18n)
n = 7
Molar mass = (142 + 18n)
Mass of water =
× (142 + 18n)18n =
× (142 + 18n)n = 7
