Calculate the mass volume percent of a NaCl solution in which 186 g of NaCl is dissolved in enough water to give a total volume of 3.80 L

48.95% (m/v)

Explanation:

From the question we are given;

Mass of solute, NaCl is 186 g Volume of the solvent, water as 3.80 L or 380 mL

We are required to calculate the mass volume percent of solution;

How do we calculate the mass volume percent of a solution?

To calculate the mass volume percent, we use the formula,

Mass volume percent = (mass of solute in g/Volume of solvent in mL) 100

= (186 g : 380 mL) 100

= 48.95%

Therefore, the mass volume percent of a NaCl solution is 48.95% (m/v).
