Question: what is the formula for finding the percentage by mass and volume of solution?
Answer: Percent by mass (m/m) is the mass of solute divided by the total mass of the solution, multiplied by 100 %. What is the percent by mass of a solution that contains 26.5 g of glucose in 500 g of solution? Percent by volume (v/v) is the volume of solute divided by the total volume of the solution, multiplied by 100 %.
