How many grams of water are contained in 75.0 grams of a 6.10% aqueous solution of KPO?
(a) 75.0 g
(b) 73.2 g
(c) 70.4 g
(d) 68.1 g
The percentage of KPO in the solution is 6.10%, which means that the remaining 93.90% is water.
Therefore, the amount of water in the solution is 75.0 grams x 93.90% = 70.425 grams.
Rounded to the nearest tenth, the answer is (c) 70.4 grams.
