If a .05 gram pill of aspirin is dissolved into 50 grams of water, what is the
percent by mass concentration of aspirin in water?

Answers

Answer 1

Answer:

0.10 % w/w

Explanation:

The percent by mass (%w/w) is defined as one hundred times the ratio between the mass of solute (In this case aspirin, 0.05g) and the mass of solution (Mass solute + mass of water = 0.05g + 50g = 50.05g). The percent by mass is:

0.05g Aspirin / 50.05g * 100 =

0.10 % w/w
