A tank c ontains 10,000 gallo ns of a so lution that is 5 percent sodium c hloride by volume.
If 2500 gallons of water evaporate fro m the tank, the remaining solutio n will be
approximat ely what perc entage of sodium chlo ride?
(a) 3.33% (b) 6.66% (c) 8.9% (d) 10%

Read Solution (Total 3)

6.66%

Vol of sod chloride = 5*10000/100 = 500 gallons by vol
vol of solution after evaporation of 2500 gallon of water = 7500 gallons.
% of sod chloride in final sol = 100*500/7500= 20/3= 6.66%
