Question
1. Vinegar contains 5.0 g of acetic acid, CH;COOH, in 100.0 mL of solution.
Calculate the molarity of acetic acid in vinegar.
![As a rough estimate, 85 g divided by 75 g/mol is about 1 mol. If you
divide 1 mol by 0.4 L you get 2.5 M. This approximation agrees with
0.4000 L
ol/L = 2.85 M KCI
O Verify your results.
