Question

What is the celsius temperature of 100.0 g of chlorine gas in a 40.0-L container at 800 mm Hg?

Answer 1

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"`?
