Calculate molarity of naoh solution if the density if solution is 1.2g

1.	Calculate molarity of naoh solution if the density if solution is 1.2g/ml and the percentage of solute is 25 % by mass of solution
Answer» MOLARITY =(10densitymass %)/MOLECULAR mass =(101.225)/40 =7.5

Calculate molarity of naoh solution if the density if solution is 1.2g/ml and the percentage of solute is 25 % by mass of solution

Answer»

MOLARITY =(10*density*mass %)/MOLECULAR mass

=(10*1.2*25)/40

=7.5
