How many grams of NaBr are needed to prepare 34.9 g of 4.75% (w/w) NaBr solution in water? How many grams of water are needed? How many milliliters are needed, given that the density of water at room temperature is 0.988 g mL? mass of NaBr = Hint Assistance Used Recall that the % means (w/w) percentage. mass of water = Hint Assistance Used Since the solution is made up of both NaBr and water, and we know the mass of the NaBr, how can we calculate the mass of water? volume of water= mL Hint Assistance Used What is the relationship between mass and density?
