An autopipette was used to place 5.00 mL of commercial bleach, weighing 5.560 g, into a volumetric flask. It was then diluted to a total volume of 50.00 mL. A 10.00-mL sample of the diluted solution was placed in an
Erlenmeyer flask. What is the mass, in grams, of commercial bleach in the 10.00-ml sample of the diluted
solution in the Erlenmeyer flask?

1.112 grams

Explanation:

The mass of commercial bleach in the 10.00 mL sample of the diluted solution in the Erlenmeyer flask would be 1.112 grams.

5.00 mL containing 5.560 g of bleach was diluted to a total volume of 50.00 mL. This means that there is 5.560 g of bleach in the 50.00 mL of the diluted sample. 10.00 mL was taken out of the 50.00 mL dilution:

50.00 mL contains 5.560 g of bleach

10.00 mL of the sample will, therefore, contain:

                      5.560 x 10.00/50.00 = 1.112 g

10.00 mL of the sample will contain 1.112 g of bleach.
