, Chemical Properties (Solution reactivity)



Mass/Volume Percent (M/V %)

Amount of solute = Mass of solute in grams

Amount of solution = Volume of solution in milliliters

M/V % = Amount of solute/Amount of solution * 100%



Examples

Calculate the percent composition or % (m/V) of 2.00 x 10 2 mL containing 20.0 g sodium
chloride




Calculate the number of grams of glucose in 7.50 x 10 2 mL of a 15.0% solution
