ANSWER
Choice 3, assuming you were not holding your breath,
is correct. The
number of moles of glucose must first be determined (5.42/180 =
0.030 1 moles), then this is multiplied by 6 to account for the stoichiometric
ratio between glucose and oxygen. From
this PV = nRT may be used with the appropriate
substitutions.
