How many moles of NaCl are in 2,719 mL of a 6.32 M solution?
Mademuasel [1]

Answer:

17.18 moles of NaCl are in 2,719 mL of a 6.32 M solution.

Explanation:

Molarity=\frac{\text{Moles of substance}}{\text{Volume of solution in L}}

We have:

Molarity of the NaCl solution = 6.32 M

Volume of the NaCl solution = 2,719 mL =2,719 × 0.001 L= 2.719 L

1 mL = 0.001 L

Let the moles of NaCl be n.

6.32 M=\frac{n}{2.719 L}

n=6.32M\times 2.719 L=17.18 mol

17.18 moles of NaCl are in 2,719 mL of a 6.32 M solution.
