Question

A pupil wants to find the density of an oil. She uses a chemical balance which measures to the nearest gram (g). She places an empty measuring cylinder on to the balance.
She pours some oil into the cylinder. The level of oil in the measuring cylinder is shown below in an attachment (named Assignment Diagram).

Use this data to find the density of oil.

Answer 1

Answer:

2.29g/cm3.

Explanation:

The following data were obtained from the question.

Mass of the oil = 172g

Volume of oil = 75cm3

Density =..?

Density of a substance is simply defined as the mass of the substance per unit volume of the substance. It is represented mathematically as:

Density = Mass /volume

With the above formula, we can calculate the density of the oil as shown below:

Density = Mass /volume

Density = 172g/75cm3

Density = 2.29g/cm3.

Therefore, the density of the oil is 2.29g/cm3.
