Calculate the milligrams of Cl (35.453 g/mol) in a 3.03 g sample of cleaning solution containing 22.1 wt% NaOCl (74.44 g/mol). NaOCl is the only source of Cl in this solution.


Expert Answer

Step 1

Given information:

Weight percentage of NaOCl = 22.1 %

Molar mass of NaOCl = 74.44 g/mol

Molar mass of chlorine = 35.453 g/mol

Mass of sample = 3.03 g

Step 2

As the sample contain 22.1 % NaOCl by weight and mass of sample is 3.03 g. Thus, the mass of NaOCl in sample will be calculated as follows:
