Question

If a solution is 65 Liters and has 13 moles of NaCl dissolved in it what is the molarity of NaCl in this solution? *

Answer 1

Answer:

Molarity = 0.2 M

Explanation:

Given data:

Number of moles of NaCl = 13 mol

Volume of solution = 65 L

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 put the values in formula.

Molarity = 13 mol / 65 L

Molarity = 0.2 mol/L

   mol/L = M

Molarity = 0.2 M
