The density of the object is 1.96 g/cm³.
Mass = 73.5 g
Volume = 82.5 mL – 45.00 mL = 37.5mL = 37.5 cm³
Density = mass/volume = 73.5 g/37.5 cm³ = 1.96 g/cm³
Answer:
Option (D)
Explanation:
Oil (crude and petroleum) is one of the major resources on earth in which the economy of a country is largely dependent on. These are non-renewable resources, which take thousands to million years of years in order to form.
