Question

10-27. A 10.231-g sample of window cleaner containing
ammonia was diluted with 39.466 g of water. Then 4.373 g of
solution were titrated with 14.22 mL of 0.106 3 M HCl to
reach a bromocresol green end point.
(a) What fraction of the 10.231-g sample of window cleaner
is contained in the 4.373 g that were analyzed?
(b) How many grams of NH3 (FM 17.031) were in the 4.373-g
sample?
(c) Find the weight percent of NH3 in the cleaner.
