The volume (in l) that would be occupied by 5.00 mol of o2 at stp is
a. 0.411 l.
b. 22.4 l.
c. 41.6 l.
d. 112 l.

At STP, temperature is 273.15 K and the pressure is at 1 atm. The volume occupied by the system given above can be calculated by using the ideals gas equation assuming that O2 is an ideal gas.

PV = nRT
V = nRT / P
V = 5.00 mol (0.08206 L atm / mol K ) (273.15) / 1 atm
V = 112 L

Therefore, the correct answer is option D.

Julia would be observing a. static electricity was caused by her sweater rubbing against her shirt and transferring electrons. she didn't touch anything metal, so that would cancel out b.she most likely didn't rub her sweater against her hair either, so that cancels out c.she also didn't scoot across the carpet while trying to take her sweater off, that cancels out d.so that leaves a.a. is correct.
