Question

What is the weight in pounds of a gallon of oil that has a specific gravity of .86

Answer 1

Mass of oil will be 7.176 pound

Step-by-step explanation:

We have given specific gravity of oil = 0.86

We know that specific gravity is given by
`specific\ gravity=(density\ of\ oil)/(density\ of\ water)`

`0.86=(density\ of\ oil)/(1000)`

Density of oil =
`860kg/m^3`

We have given volume of oil = 1 gallon

We know that 1 gallon = 0.003785
`m^3`

So mass of oil = volume ×density

mass = 0.003785×860 = 3.2551 kg

We know that 1 kg = 2.2046 pound

So 3.2551 kg = 3.2551×2.2046 = 7.176 pound
