Question

calculate the mass/volume percent of a nacl solution in which 119 g of nacl is dissolved in enough water to give a total volume of 4.24 l .

Answer 1

The formula for mass/volume percent is:

`\displaystyle \text{Mass/Volume percent} = \left(\frac{{\text{Mass of solute}}}{{\text{Volume of solution}}}}\right) * 100`.

Given:

Mass of NaCl = 119 g

Total volume of the solution = 4.24 L

Plugging in the values into the formula:

`\displaystyle \text{Mass/Volume percent} = \left(\frac{{119 \, \text{g}}}{{4.24 \, \text{L}}}}\right) * 100`.

Now, let's perform the calculation:

`\displaystyle \text{Mass/Volume percent} = \left(\frac{{119}}{{4.24}}\right) * 100`.

Calculating this expression, we have:

`\displaystyle \text{Mass/Volume percent} \approx 28.1`.

Therefore, the mass/volume percent of the NaCl solution is approximately 28.1%.
