Question #1386

An engineer weighs a sample of mercury ( density= 13.6 × 103 kg/m3) and finds that the weight of the sample is 4.3 N.

What is the sample’s volume? The acceleration of gravity is 9.81 m/s2 .

Answer in units of m3.

What is the sample’s volume? The acceleration of gravity is 9.81 m/s2 .

Answer in units of m3.

Expert's answer

We have to find the mass of the sample:

m = F/g = 4.3/9.81 = 0.438 kg

Thus the volume of the sample is

V = m/ρ = 0.438/13.6 × 10

m = F/g = 4.3/9.81 = 0.438 kg

Thus the volume of the sample is

V = m/ρ = 0.438/13.6 × 10

^{3}= 3.2 × 10^{-5}m^{3}.
