Question

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

Answer 1

Answer:

Mass of oil will be 7.176 pound

Explanation:

We have given specific gravity of oil  = 0.86

We know that specific gravity is given by $specific\ gravity=\frac{density\ of\ oil}{density\ of\ water}$

$0.86=\frac{density\ of\ oil}{1000}$

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
