Answer to Question #108811 in General Chemistry for Bianca Barrios

Question

calculate the molarity of a kcl solution made by adding 15.00ml of distilled water to 48.00ml of 0.75m kcl solution

Answer 1

С(KCl)= n(KCl)/V_solution;

n(KCl)= 0.048*0.75=0.036 mol;

V_solution= 0.048+0.015=0.063 L

C(KCl)=0.036/0.063 = 0.57 M

Answer: the molarity of a kcl solution is 0.57 M
