Question

What is the molarity of a solution containing 15.2 g of KCl in 354 mL of solution?

Answer 1

Answer #1

Ans--- Given 15.2 g of KCl , first we have to calculate the moles of Kcl

we know molar mass of KCl=74.55

Therefore mole of Kcl = 15.2 g Kcl * 1mol kcl/74.55 g kcl

=0.203 moles of kcl

we know molarity = moles of solute / litters of solution

= 0.203/0.354

molarity =0.573 m
