Question

A liquid of mass 10 kg is enclosed in a cylinder of radius 1 m and length 5 m, what is the density of liquid?

(a) 0.54 kg/m^3

(b) 0.44 kg/m^3

(c) 0.63 kg/m^3

(d) 0.83 kg/m^3

The question was asked in examination.

Query is from Density topic in portion Moles, Density & Concentration of Basic Chemical Engineering

Answer 1

The correct option is (c) 0.63 kg/m^3

The best explanation: Volume of cylinder = π(1^2)5 = 5π m^3, => Density = 10/5π = 0.63 kg/m^3.
