Final answer:
To calculate the mass/volume percent, use the formula % m/v = (mass of solute in grams / volume of solution in mL) x 100%. For 24.5 g of NaCl in 61.0 mL of solution, the calculation yields a mass/volume percent of 40.2% m/v.
Step-by-step explanation:
Calculating the Mass/Volume Percent of a NaCl Solution
To calculate the mass/volume percent (m/v) of a solution, we need to know the mass of the solute (NaCl in this case) and the volume of the solution. The formula is as follows:
% m/v = (mass of solute in grams / volume of solution in mL) x 100%
For the given problem, we have 24.5 g of NaCl in 61.0 mL of solution. Plugging in these values into the formula:
% m/v = (24.5 g NaCl / 61.0 mL solution) x 100%
After performing the calculation, the mass/volume percent of the NaCl solution to three significant figures is:
40.2% m/v
