A small thermometer is broken in a closed room of dimensions

6 \times 5 \times 3 \text{ m}^3

and the mercury shows the equilibrium :

\text{Hg}(l) \rightleftharpoons \text{Hg}(v)

at 27°C. The atomic mass of Hg is 200.5 and vapour pressure of Hg at 27°C is 0.002 mm. Is it dangerous to enter the room if safety limit to

\text{Hg}(v)

0.05 \text{ mg/m}^3
