1000 mL will weigh 1800g mass of H 2 ​ S O 4 ​ present = 1800 gm number of mole of H 2 ​ S O 4 ​ = actual m a s s / m o l a r m a s s = 1800 ÷ 98 = 18.36 thus molarity of a stock solution is 18.36 M To prepare 500 mL of 0. 9 M solution, M 1 ​ V 1 ​ = M 2 ​ V 2 ​ 18.36 x A = 0.9 x 500 mL 1 8 . 3 6 4 5 0 ​ = 24.5 ml Hope it helps
