Answer:

#P=1482atm#

Explanation:

Assuming that methane is behaving ideally, we can then calculate the pressure using the ideal gas law:

#PV=nRT#.

We will need first to find the number of mole of methane using the mass 885.5 g:

#n=m/(MM)=(885.5 cancel(g))/(16.04cancel(g)/(mol))=55.20molCH_4#

Then, to find the pressure, we can rearrange the expression of the ideal gas law to be:

#P=(nRT)/V=(55.20cancel(mol)xx0.08201(cancel(L)*atm)/(cancel(K)*cancel(mol))xx265.1cancel(K))/(0.810cancel(L))=1482atm#
