Q.5= How much salt is in a mixture containing 10 gallons of an 11% salt solution
 and 6 gallons of a 7% sal solution?

anonymous · Answer

Salt = (10*.11 + 6*.07)gallons = (1.1 + .42)gals = 1.52 gals.

Salt + Water = Mixture => Water = Mixture - Salt

How many gallons of mixture do you have?
How many gallons of salt are in it?

% Water = gallons of Water/ gallons of Mixture
