4.62 (a) Calculate the molarity of a solution made by dissolv- ing 12.5 grams of Na CrO, in enough water to form exactly 4. 750 mL of solution. (b) How many moles of KBr are present in 150 mL of a 0.112 M solution? (c) How many milliliters of 6.1 M HCl solution are needed to obtain 0.150 mol of HCl?
