Current Attempt in Progress

A $2\mathrm{.}00{10}^4-$liter storage tank was taken out of service to repair and reattach a feed line damaged in a collision with a tanker$.$

The tank was drained and then opened several days later for a welder to enter and perform the required work.

No one realized, however that a large volume of liquid nonane $(C_9{H}_{20})$ remained in a collection sump at the bottom of the tank after the draining had been completed.

Nonane has a lower explosion limit of $0\mathrm{.}80$ mole$\%$ and an upper explosion limit of $2\mathrm{.}90$ mole$\%($i$.$e$,$ nonane$-$air mixtures at $1$ atm can explode when exposed to a spark or flame if the nonane mole fraction is between the two given values$).$

Vapor Pressure

Use the Antoine equation $(6\mathrm{.}1-4)$ to estim$$te the temperature at which the system would have to equilibrate in order for the gas in the tank to be at the lower explosion limit $(P-1$ atm$).$
