Answer:

Approx. #6*mol#.

Explanation:

#"Number of moles"# #=# #"Mass of methane"/"Molar mass of methane"#

#=(96.00*cancelg)/((12.011+4xx1.00794)*cancelg*mol^-1)#

#=??mol#

Note that the quotient is dimensionally consistent. We want an answer in moles, and we get an answer in #1/(mol^-1)=mol# as required.

At #STP#, what volume would this quantity of methane occupy?
