PLEASE HELP ASAP!! 57. Sodium sulfate is used in the manufacture of detergents.
a. Identify each of the component elements of sodium sulfate, and write the compound's chemical formula.
b. Identify the compound as ionic or covalent.
c. Calculate the percent by mass of each element in sodium sulfate.

See Explanation

Explanation:

The formula of sodium sulphate is Na2SO4. The component atoms in the compound are; sodium, sulphur and oxygen.

The compound is ionic. it is composed of sodium ions and sulphate ions.

The molar mass of sodium sulphate = 142 g/mol

percentage by mass of sodium =  2* 23/142 * 100 = 32.39 %

percentage by mass of sulphur = 32/142 * 100 = 22.5%

percentage by mass of oxygen = 4 * 16/142 * 100 = 45.1 %
