Question

Mercury has a density of 13.6 g/cm3. What is the mass of a sample of mercury in a cylindrically shaped vial of radius 8 cm and height 10 cm?

Answer 1

The mass of the sample of mercury is 11,648 g.

To calculate this, first calculate the volume of the vial:

Volume = πr2h

Volume = 3.14 x (8 cm)2 x (10 cm)

Volume = 2,048 cm3

Then, calculate the mass of the sample of mercury:

Mass = Density x Volume

Mass = 13.6 g/cm3 x 2,048 cm3

Mass = 11,648 g
