given a density of 1.25lb per gallon an volume of 1.6 gallon find the mass.

To find the mass, we need to use the equation:

mass = density × volume

Given that the density is 1.25 lb per gallon and the volume is 1.6 gallons, we can plug these values into the equation:

mass = 1.25 lb/gal × 1.6 gal

To find the answer, we multiply the values:

mass = 2 lb

Therefore, the mass is 2 pounds.
