Explain 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 usually as %concentration=amountofsoluteamountofsolutionÃ100% Depending on the situation a percent concentration might be computed for mass/mass, volume/volume or mass/volume.

Compute the mass percent of a solution that is prepared by adding 46.9g of NaOH to 303g of H2O.
