Calculate the mass/volume percent, % (m/v) for the solute in each of the following solutions. 70 g of Na2SO4 in 250 mL of Na2SO4 solution? 37 g of sucrose in 335 mL of a carbonated drink?
8. Calculate the mass/volume percent (m/v) for the solute in a 473 mL of coffee with 12 g added sucrose (3 points) Answer
Isopropyl alcohol is mixed with water to produce a 38.0% (v/v) alcohol solution. How many milliliters of each component are present in 875 mL of this solution? Assume that volumes are additive. alcohol: mL water: ml The mass of solute per 100 mL of solution is abbreviated as (m/v). Mass is not technically the same thing as weight, but the abbreviation (w/v) is also common. How many grams of sucrose are needed to make 695 mL of a 38.0% (w/v)...
