AnnZ [28]3 years ago
6 0

<u>Answer:</u> The number of moles of NaCl in the solution are 0.0875 moles.

<u>Explanation:</u>

To calculate the number of moles of NaCl, we use the equation that is used to calculate molarity, which is:

\text{Molarity of the solution}=\frac{\text{Moles of solute}}{\text{Volume of solution (in L)}}

We are given:

Molarity of NaCl solution = 0.35 mol/L

Volume of solution = 250 mL = 0.250 L      (Conversion factor:  1L = 1000 mL)

Putting values in above equation, we get:

0.35mol/L=\frac{\text{Moles of NaCl}}{0.250L}\\\\\text{Moles of NaCl}=0.0875mol

Hence, the number of moles of NaCl in the solution are 0.0875 moles.
