Question

Camphor is used as solvent to determine the molecular mass of non-volatile solute by Rast method because for camphor

• A. molar depression constant is high
• B. melting point is high
• C. being cheap
• D. all the above

Answer 1

The correct option is A

molar depression constant is high

Camphor is used for the determination of molecular masses of solute bu depression in freezing point method because its molal depression constant is very high 40 km^-1
