Question

Q.1. If d is the density of a solution of a solute(molar mass = W) in a solvent and "m" is the molarity , then prove that molarity(M) of this solution is
M = (1000d m)/(1000 + mW)
Q.2. If x is the mole fraction of a solute when dissolved in pure waiter, then prove that the molarity of solution is

" molarity* of solution is "
* molality
Molality (m) = (500x)/(9-9x)
