#n=(PV)/(RT)#

#P# #=# #9.75*atm#;

#V# #=# #33.81*L#

#R# #=# #0.0821*L*atm*K^-1*mol^-1#

#T# #=# #323*K#

You ave just got to fill in the dots to give an answer in #"MOLES"#

This will be inevitable dimensionally:

#(cancel(atm)xxcancelK)/(cancelL*cancel(atm)*cancel(K^-1)*mol^-1xxcancelK)#

That is you get an answer in #1/(mol^-1)=mol" as required."#
