According to the explanation given in a previous session, now we have 1500 grams of bleach solution and a percent by mass of 3.62% of NaOCl, therefore we will be using again the formula for percent by mass, but now, to find the mass of the solute:
%mass = mass of the solute/mass of the solution
0.0362 = m/1500
m = 54.3 grams of NaOCl in this solution
