A liquid weighing 160 g has a volume of 180 cm3. Find its density. What is this substance?

Specified fluid density:

ρ = m / V, where m is the mass of the desired liquid (by the condition m = 160 g = 0.16 kg), V is the volume occupied by the liquid (V = 180 cm3 = 180 * 10-6 m3).

ρ = m / V = 0.16 / 180 * 10-6 = 889 kg / m3. Substance – engine oil or mineral oil.

One of the components of a person's success in our time is receiving modern high-quality education, mastering the knowledge, skills and abilities necessary for life in society. A person today needs to study almost all his life, mastering everything new and new, acquiring the necessary professional qualities.
