A solution of hydrogen peroxide (H2O2) in water with a volume of 50.0 mL is diluted by adding 70.0 mL of water. Calculate the solution’s new concentration given the following original concentrations. (Addition of 70.0 mL of water is equivalent to adding 70.0 g of water since the density of water is 1.00 g/mL.) Enter a number only. Do not spell. Do not use scientific notation. Calculate your answer to 3 significant figures. a) 2.00%(v/v) %(v/v) H2O2 b) 2.00%(m/m) %(m/m) H2O2
