Answer #1

Weight / Volume percent (% w/v) = [Weight of solute (g) / Volume of solution (mL)] * 100

                                                = (250 / 1000 * 5) * 100

                                                = 5 % w/v

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=amountofsoluteamountofsolution×100% Depending on the situation, a percent concentration might be calculated for mass/mass, volume/volume, or mass/volume. A.) Calculate the mass percent of a solution that is prepared by adding 27.6 g of NaOH to 421 g of H2O. Express your answer numerically. B.) Calculate the mass/volume percent of...
