An object weighing 9.6 g is placed in a graduated cylinder displacing the volume from 10.0 ml to 13.2 ml.
what is the volume of this object?

Density = mass/ volume

mass= 9.6 g

Volume of the object = 13.2-10.0 =3.2 ml=3.2 cm³

1ml =1 cm³

D=9.6g/3.2 cm³ = 3.0 g/cm³

Explanation:

a gas, having a molecular weight of 13 kg/kmol and a kinematic viscosity of 0.25 cm2/s, flows through a pipe 0.25 m internal diameter and 5 km long at the rate of 0.4 m3/s and is delivered at atmospheric pressure.
