Question

(i) 24g of naoh is dissolved in 300ml water.calculate the molarity of the solution. (ii)the density of a 3m solution of nacl is 1.25g/ml. calculate the molality of the solution.​

Answer 1

Answer:

molarity is 2M

Explanation:

as molarity =mass of solute÷GMM *

× 1000÷ volume of solutuon

Answer 2

Answer:

i) 4.4

Explanation:

M=W×100/m×v

=> 24×1000/18*300
