At 100°C and 1 atm, if the density of liquid water is `1.0 g cm^(-3)` and that of water vapour is 0.0006 gcm-3 , then the volume occupied by water molecules in 1 litre of steam at that temperature is:

Options

A. `6 cm^(3)`
B. `60 cm^(3)`
C. `0.6 cm^(3)`
D. `0.06 cm^(3)`

Answer

D

Explanation

Mass of water in `1 L` steam `= 1000 xx 0.00006 g`
`= 0.06 g`
Volume of `0.06 g` water `= (0.06)/(1 g cm^(-3)) = 0.06 cm^(3)`
