So what you need to do is take 15 gallons and convert it into liters by multiplying by a ratio, which is given (1 gallon = 3.79 liters; 1g : 3.79L). The way you do this is by making sure the equation has a ratio that has the gallons on the bottom so that when you calculate how many liters there are, the gallons cancel each other out, leaving you with liters.

Explanation:
= Initial mass of water = 100 g
c = Specific heat of water
= Temperature difference of the initial mass of water =
= Amount of water that is mixed = 75 g
= Temperature difference of the mixed mass of water =
= Equilibrium temperature
The heat balance of the system is
The final temperature of the mixed water is .
