Question

This 200 mL bottle of cooking oil weighs 174 g. Calculate the
density of the oil.

Answer 1

Density is calculated by dividing the mass of a substance by its volume. In this case, the mass of the cooking oil is 174 g and its volume is 200 mL (or 0.2 L). So the density of the oil can be calculated as follows:

Density = Mass / Volume Density = 174 g / 0.2 L Density = 870 g/L

So the density of the cooking oil is approximately 870 g/L.
