The concentration 5% (w/v) means that 5 g of acetic acid (solute) are present in 100 mL of the solution. Using the density you determined in the previous problem, determine the mass of water (solvent) in 100 mL of the solution. Follow the guided steps below.
A. Determine the mass of 100. mL of the solution by using the density. Express your answer in three significant figures.)
B. The mass of the solution should be the sum of the mass of the solvent and the mass of the solute. Now determine the mass of the solvent
