Question

Crude oil is sold in units of barrels, where 1 barrel=160 liters. Assume that crude oil has a density of 823.0 kg/m^3

Answer 1

We have the next information

1 barrel=160 L

First we need to convert the liter to m^3

1 m^3=1000L

$\frac{160L(1m^3)}{100L}=0.16m^3$

160L=0.16m^3

then we have the next formula about density

$\text{density}=\frac{\text{mass}}{\text{volume}}$

Volume=0.16m^3

mass=?

density=823 kg/m^3

we substitute the values

$823=\frac{m}{0.16}$

Then we isolate the mass

$\begin{gathered} m=823(0.16) \\ m=131.68\text{ kg} \end{gathered}$

ANSWER

The mass of 1 barrel of crude oil is 131.68 kg
