Question

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

Answer 1

Answer:

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).
