Question

A bottle full of mercury has a mass of 720 grams,when full of water its mass is 90 grams.Calculate the volume of the empty density bottle,the mass of the bottle and the density of the mercury?

Answer 1

Mass of bottle is 40g.

$$RD=\frac{720-40}{90-40}=13.6$$

$$\rho_{Hg}=13600\frac{kg}{m^3}$$

$$0.09-0.04=(1000)(9.8)V$$

$$V=5.1\cdot10^{-6}m^3$$
