Question

6.02(10^23) molecules of urea are present in 100 ml of its solution . the concentration of solution is

Answer 1

It is 1 mole of urea
So 1 mole is present in 0.1 lite of solution
Molarity = no.of moles of solute / volume of solution in litres
So 1/0.1=10M
It is the concentration expressed in molarity
