Answer:

This question is ill-proposed..........I get approx.. #136# #""^@C#

Explanation:

#1*atm# will support a column of mercury that is #"760 mm"# high. Often we can use the length of a mercury column to measure a reduced pressure, using the relationship, #1*atm-="760 mm Hg"#.

If we try to use a column of mercury that is higher than #"760 mm"#, we risk getting mercury all over the lab, where it will inhabit every nook and every cranny.

We assume a pressure of #"800 mm Hg"/("760 mm Hg"*atm^-1)=1.053*atm.#

We use the Ideal Gas equation, #T=(PV)/(nR)#

#(1.053*cancel(atm)xx40.0*cancelL)/((100.0*cancelg)/(70.9*cancelg*cancel(mol^-1))xx0.0821*cancelL*cancel(atm)*K^-1*cancel(mol^-1))=409.9*K#

What is this temperature in #"degrees Celsius"#?
