A solid mixture made up of 75% of solid A and 25% of solid B by mass is to be dissolved in 250.0 ± 0.5 mL of water. Assuming that the solid mixture is completely soluble in water, how many grams of the solid mixture must be used to obtain a 0.500 ± 2% molal solution of solid A. The formula mass of solid A is 101.11 g/mol while the formula mass of solid B is 174.2592 g/mol. The density of water at the temperature of the experiment is 0.9972995 g/mL. What absolute uncertainty will be associated with your mass measurement?
