If you dilute 50 ml of a 25% solution of table salt to 100 ml,
what will be the resultant percentage strength?
:
Let x = the percent (in decimal form), when 100 ml is added
:
.25(50) = x(100 + 50)
12.5 = 150x
x = 12.5%2F150
x = .0833 = 8.33%
:
:
Check solution by finding the amt of salt
.25(50) = .0833(150)
12.5 = 12.5
