What is the molarity of 200. mL of solution containing 4.50 moles of ZnCl2?

Molarity of solution = 0.9 M

Explanation:

Given data:

Moles of ZnCl₂ = 4.50 mol

Volume of solution = 200 mL

Molarity of solution = ?

Solution:

Molarity is used to describe the concentration of solution. It tells how many moles are dissolve in per litter of solution.

Formula:

Molarity = number of moles of solute / L of solution

Now we will convert the volume in L.

200 mL×1 L/1000 mL = 0.2L

M = 4.50 mol / 0.2 L

M = 0.9 M
