Freezing point of a 4% aqueous solution of X is equal to freezing point of 12% aqueous solution of Y. If molecular weight of X is A, then molecular weight of Y is :
Molar Mass -
The mass of one mole of a substance in grams is called its molar mass.
Molar mass of water = 18 g mol-1
Mole Concept -
One mole is the amount of a substance that contains as many particles or entities as there are atoms in exactly 12 g (or 0.012 kg) of the 12C isotope.
one mole = 6.0221367 X 1023
