Answer: 20%
Explanation: Relative humidity is the ratio of amount of moisture in the air to the maximum amount of moisture that could exist in the air at a specific temperature.
Thus [tex]{\text {relative humidity}=\frac{\text {amount of moisture}}{\text {maximum amount of moisture}}\times 100\%[/tex]
[tex]{\text {relative humidity}=\frac{6g/m^3}{30g/m^3}\times 100\%=20\%[/tex]
