A certain vinegar is 6.02% acetic acid (HC2H3O2) by mass. How many grams of HC2H3O2 are contained in a 355mL bottle of vinegar? Assume a density of 1.01g/mL.

density = 1.01 g/mL so what is the mass of 355 mL?
1.01 g/mL x 355 mL = ?? grams.
How much of that is HC2H3O2? It is 6.02%; therefore,
?? grams x 0.062 = xx grams HC2H3O2.

355mL (1.01g/mL) (0.0602) = 21.6g
