Answer:
3.12%
Explanation:
Mass percent is defined as 100 times the ratio between mass of solute (In this case, acetic acid) and total mass of the solution (Mass of solute + Mass of solvent). The equation is:
Mass percent = Mass solute / Total mass * 100
Replacing:
3.06g Acetic Acid / 98.05g * 100
Mass percent of a vinegar solution = 3.12%
Given that;
Total mass of solution = 98.05 g
Amount of acetic acid = 3.06 g
Find:
Mass percent of a vinegar solution
Computation:
Mass percent of a vinegar solution = [3.06 / 98.05]100
Mass percent of a vinegar solution = 3.12%
