Acylindrical glass tube 12.7 cm in length is filled with mercury (density =13.6 g/ml). the mass of mercury needed to fill the tube is 105.5 g. calculate the inner diameter of the tube (volume of a cylinder of radius r and length h is v=ïr2h).

The inner diameter of the tube is 0.4410 cm.

Explanation:

Height upto which mercury is filled = 12.7 cm

Mass of mercury = 105.5 g

Density of mercury = 13.6 g/mL =

Volume of mercury:

A mercury in cylindrical glass tube is at height of 12.7 cm.

The radius of the inner diameter of the glass tube = r

Volume of cylinder =

r = 0.4410 cm.
