Question

A solution of a substance containing 1.05g per 100mL was found to be isotonic with 3% glucose solution the molecular mass of substance is

Answer 1

Answer:

isotonic means osmotic pressure is the same for both.

since OP=cRT

c is concentration,we can equate both the concentration terms.

so 3/180=1.05/M

so M=63u
