Answer:
The water would weigh 25.04 pounds.
Step-by-step explanation:
Mass = volume × density
Given;
Volume of water = 3 gallons of water
Density of water = 1000kg/m^3
Converting the density to pounds per gallon.
Density = 1000kg/m^3 × 2.205pounds/kg × 1/264.172gallon/m^3
Density = 8.347 pounds/gallon
Therefore, the mass can be calculated as;
Mass = 3 gallons × 8.347pounds/gallon
Mass = 25.04 pounds
Therefore, the water would weigh 25.04 pounds.
