Chemistry Question on States of matter

What is the density of water vapour at boiling point of water?

A

1×10−4 g cm−31 \times 10^{-4} \,g \,cm^{-3}

B

1 g cm−31 \,g \,cm^{-3}

C

6×10−4 g cm−36 \times 10^{-4} \,g \,cm^{-3}

D

4×10−4 g cm−34 \times 10^{-4} \,g \,cm^{-3}

Answer

6×10−4 g cm−36 \times 10^{-4} \,g \,cm^{-3}

Explanation

Solution

The density of water never has absolute value because it varies with temperature. The density of water vapour at boiling point (100∘C)\left(100^{\circ} C \right) of water is 6×10−4g cm−36 \times 10^{-4} g\, cm ^{-3}
