What volume at #"SLC"# is occupied by an #88*g# mass of carbon dioxide?

#A.# #49L;#
#B.# #24.5L;#
#C.# #98*L;#
#D.# #"Cannot be determined."#

Answer 1

Option #A#, #49# #L#.

Now you have #(88.0*g)/(44.0*g*mol^-1)# #=# #2*mol# #CO_2(g)#.

For this molar quantity of course we could solve the Ideal Gas equation, but, we know that #1# #mol# of Ideal Gas has a volume of #24.5# #L# under standard conditions of #298# #K# and #1# #atm#. I think that this is even given as supplementary information in the A level exams. Since we have #2# #mol#, there will be twice this molar volume.

Because we are operating in a regime of moderate pressures and reasonably high temperatures, the actual experimental volume will be very close to this value.

The volume occupied by an 88 g mass of carbon dioxide at standard temperature and pressure (STP) is approximately 22.4 liters.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
