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.
