ethanol has a density of 0.789 g/cm3, how many pounds of ethanol would be in a drum containing 7.0 gallons of ethanol

Sagot :

From the density of ethanol given, the number of pounds of ethanol in the drum will be 46.099 pounds.

How to calculate density

Density of ethanol = 0.789/cm³

1 gallon = 3785.4ml

Volume of ethanol = 7 gallons = 7 × 3785.4ml = 26497.8ml

Mass of ethanol = Volume × Density.

= 26497.8 × 0.789

= 20906.764g

Since 1g = 0.002205 pounds, the mass of ethanol will be:

= 20906.764 × 0.002205

= 46.099 pounds.
