What isthe mass of NaOCI in a 2.5-kg bottle of bleach?SolutionThis is a relatively easy question. The quoted percentage means that for every 100 g csolution, 3.62 g are the solute, sodium hypochlorite. You can set up a proportion, ornote that the percentage is constant:3.62% = 0.0362Thus: kg NaOCI = 0.0362 x 2.5 kg = 0.0905 kg NaOCI = 90.5 g NaOCI-OR-3.62 g100.0 gX2500.0 gx = 90.5 g NaOCI

Matter and Measurement

In the universe, there is matter, energy, and void space. The universe contains energy and void space. The definition of matter can be considered as something which possesses mass and consumes space. Chemistry is that branch of science which deals with the study of matter. Under chemistry, nature, composition, and the changes occurring to matter are discussed.

Calculate the mass percentage of NaCl in a solution containing 1.50 g sodium chloride
in 50.0 g of water.
Solution
Thus:
Total mass of solution = 1.50 g + 50.5 g = 51.5 g
% NaCl = 1.50g x 100 = 2.91 % NaCl
51.5 g
Practice Exercise 3b
A commercial bleaching solution contains 3.62 mass % sodium hypochlorite. What is
the mass of NaOCI in a 2.5-kg bottle of bleach?
Solution
This is a relatively easy question. The quoted percentage means that for every 100 g c
solution, 3.62 g are the solute, sodium hypochlorite. You can set up a proportion, or
note that the percentage is constant:
3.62% = 0.0362
Thus: kg NaOCI = 0.0362 x 2.5 kg = 0.0905 kg NaOCI = 90.5 g NaOCI
