1.	9. 0.1 mole of a chloride, XCI, combines with 10.8 g of water to form the hydrate XCI,.nH,O. What is the value of n? A 2 B 4 C 6 D 10
Answer» ANSWER: Correct OPTION is B 20 One mole of chlorine = 71 g. Molecular weight of MCl 2 =111g M+71=111 M=111−71=40 2g of H 2 is displaced by 40g of metal, then 1 g of H 2 is displaced by 2 40 =20 g of the metal.

Answer»

Correct OPTION is

One mole of chlorine = 71 g.

Molecular weight of MCl

=111g

M+71=111

M=111−71=40

2g of H

is displaced by 40g of metal, then 1 g of H

is displaced by

=20 g of the metal.
