Step-by-step explanation:
First, we calculate the amount if ammonia in 22 gallons of 16% ammonia solution.
16% * 22 gal = 3.52 gal
The amount of ammonia remains the same after the water evaporates, but the total amount of solution is reduced by the amount of water that evaporates.
amount of ammonia: 3.52 gal
amount of water that remains: 22 - n
desired concentration, 24% = 24/100
Equation:
(3.52)/(22 - n) = 24/100
Answer: C.
