Question

What is the molarity of a solution that contains 0.702 mol KCl in 0.98 L solution?

a. 0.68 M

c. 0.72 M

b. 0.459 M

d. 1.40 M

Answer 1

C. 0.72 M

Step-by-step explanation:

To calculate the molarity use the following equation, C=n/V

You have the molar number n which is 0.702 and the volume 0.98 L

Replace those numbers in the formula C=0.702/0.98= 0.72 M
