Question

What is the molarity of a solution made by dissolving 1.0 g of KOH in enough water to make 750 mL of solution?

Answer 1

llutions) weight of koll to be dissolved = 1 m 2 Voulme of solution - 750mL = 750 x 102 Molar mass of KOH = 56 gm/mas se, molt of Kow eight of KÖH_ Molaimass of KOH moles of KOH = 1 gm = 0.0178 moles 56gm/mal cax au ording to formulai I Molarity = moles of nolute Volume of solutiaindite Molaity = 0.017.8 male 750X10-3 L Molarity = Molarity = 0.023 molt 0.023 moll litre
