Answer :
The density of a solid with a mass of 5.00 lb and a volume of 5.00 gal is calculated by converting pounds to grams and gallons to cubic centimeters and then dividing the resulting mass by the resulting volume; it is approximately 0.1198 g/cm³.
To calculate the density of a solid if 5.00 lb has a volume of 5.00 gal, you first need to convert these units to grams and cubic centimeters (cm3), respectively. There are 453.59237 grams in a pound and 3785.41 cm3 in a gallon. So, 5.00 lb is equal to 2267.96185 grams (5 * 453.59237 g/lb), and 5.00 gal is equal to 18927.05 cm3 (5 * 3785.41 cm3/gal).
Now, density is defined as mass divided by volume. Using the conversions above:
Density = Mass / Volume
Density = 2267.96185 g / 18927.05 cm3
Density
= 0.1198 g/cm3
