Final answer:
The tank contains approximately 218 gallons of water after subtracting the weight of the empty tank from the total weight and dividing by the weight of one gallon of water.
Step-by-step explanation:
To find out how many gallons of water are in the tank, first we need to calculate the weight of the water alone. This is done by subtracting the weight of the empty tank from the total weight when the tank has water.
Weight of water: 2,323 pounds (total weight) - 504 pounds (empty tank weight) = 1,819 pounds (weight of water)
Next, we need to know how many pounds one gallon of water weighs. The standard weight of one gallon of water is approximately 8.34 pounds. To find the number of gallons, we will divide the weight of the water by the weight of one gallon of water.
Number of gallons of water: 1,819 pounds / 8.34 pounds per gallon = 218 gallons
