Question

A 0.98 M solutions of calcium chloride with a volume of 0.25 L diluted to form a 0.74 M solution. What is the new volume of the solution to the nearest hundredth of a liter?

Answer 1

The new volume of the solution is 0.33 L

Step-by-step explanation:

Step 1: Data given

The molarity of calcium chloride = 0.98 M

The volume = 0.25 L

The new molarity = 0.74 M

Step 2: Calculate the new volume

C1*V1 = C2*V2

⇒with C1 = the molarity of calcium chloride = 0.98 M

⇒with V1 = the volume = 0.25 L

⇒with C2 = the diluted molarity = 0.74M

⇒with V2 = the new volume = TO BE DETERMINED

0.98 M * 0.25 L = 0.74 M * V2

V2 = (0.98 M * 0.25 L ) / 0.74 M

V2 = 0.33 L

The new volume of the solution is 0.33 L
