What is the percent-by-mass concentration of acetic acid (ch3cooh) in a vinegar solution that contains 51.80 g acetic acid in a 1.000−l solution? the density of this solution is 1.005 g/ml.

Answer : The percent-by-mass concentration of acetic acid is, 5.15 %

Explanation : Given,

Mass of acetic acid = 51.80 g

Density of solution = 1.005 g/ml

Volume of solution = 1.000 L = 1000 ml      (1 L = 1000 ml)

First we have to calculate the mass of solution.

Now we have to calculate the percent-by-mass concentration of acetic acid.

Now put all the given values in this formula, we get:

Therefore, the percent-by-mass concentration of acetic acid is, 5.15 %

the old alchemists made significant contributions to science even though there starting premises were off a bit. their conclusions after failure would steer them into better directions for investigation. science is no more than close observation and the initial mistakes result in rethinking and retrying experiments.
