Question 5 (5 points) (08.02 LC)
Which of the following is the correct formula to calculate percent by mass? (5 points)
[Mass of solution (g) + mass of solute (g)] x 100
Oь
[Mass of solute (g) - mass of solution (g)] x 100
O
[Mass of solute (g) = mass of solution (g)] x 100
Od
[Mass of solution (g) = mass of solute (g)] x 100

Some liquids can be distilled, but only at temperatures that are so high that it is impractical, or so high the compound decomposes. explain why distillation such compounds at significantly less than atmospheric pressure (some degree of vacuum) would solve this problem.
