Some Basic Concepts Of Chemistry Question 172

Question: 1.25 g of a solid dibasic acid is completely neutralised by 25 ml of 0.25 molar Ba(OH)2 solution. Molecular mass of the acid is

Options:

A) 100

B) 150

C) 120

D) 200

Show Answer

Answer:

Correct Answer: D

Solution:

Molarity =W(gm)×1000V(ml)×molecular weight

0.25=1.25×100025×molecular weight

Molecular weight =1.25×10000.25×25=200 .
