Question

The percent concentration of a solution is a ratio of the amounts of dissolved solute and solution, expressed as a percentage. The percent concentration of a solution can be written generally as %concentration=amountofsoluteamountofsolutionÝ100% Depending on the situation, a percent concentration might be calculated for mass/mass, volume/volume, or mass/volume.

Calculate the mass/volume percent of a NaCl solution in which 167g of NaCl is dissolved in enough water to give a total volume of 4.27L .

Explanation / Answer

The concentration of NaCl is 167/4.27 = 38.40 g / L

I suppose that the density of solution 1 g/cc or 1g / ml.

So I have 1000 g of water for 38.40 g of NaCl .

Mass percent (38.40/1000)*100=3.84 % mass/volume.
