Approx. #0.2*mol# #"of neon gas."#

#n=(PV)/(RT)=(4.6*cancel(atm)xx0.84*cancelL)/(0.0821*cancel(L*atm)*cancel(K^-1)*mol^-1xx222*cancelK)#

#=??1/(mol^-1)=1/(1/(mol))=mol# as required............

Note that you did not specify the units of volume. I have ASSUMED it was #"litres"#.............

The given calculation gives UNITS of moles as required.
