Asked Sep 21, 2019
Acetic acid (HC2H3O2) is the active ingredient in vinegar. Calculate the mass percent composition of carbon in acetic acid.
Express the mass percentage to four significant figures.

Expert Answer

Step 1

The way of representation of concentration of an element in a compound or a component of a mixture is known as mass percentage.

Step 2

The mass percentage can be calculated as follows:

Mass of component Mass percent of component* -x100% Total mass of the solution

Step 3

Since, mass of acetic acid and vinegar is not given so molar mass is used in calculating mass percent of the component.

Molar mass of a substan...
