Question

Calculate the molarity of solutions prepared by dissolving 50 g of NaOH in 100ml solution

Answer 1

molarity= weight of solute× 1000/volume in litere
=> 50× 1000/100×1000
=> 2

Answer 2

★ Ello ★





mole = mass / molecular mass


=> 50 g / 39 .9

=> 1.25 mol


now ,


100 / 1000liter


=> 0.1 liter



molarity = mole / liter


=> 1.25 / 0.1

=> 12.5 mol / liter



hope it helps you dear !!


hence your answer is ★ 12 .5 mol / liter ★



$thanks$
