QUESTION 3 Determine the volume percent of a solution made by adding 46.3 mL of bleach in enough water to make
total of 175.9 mL of solution. (vol % = solute vol/ solution total vol. x 100)
QUESTION 4: If
you have 2.42 L of 1.09 M K2 CrO4 solution, calculate the grams of solute present: (find moles of
K2Cro4 present, then convert to grams)
