What mass, in grams, of oxygen gas (O2) is contained in a 10.5 liter tank at 27.3 degrees Celsius and 1.83 atmospheres? Show all of the work used to solve this problem.

ria23 · Answer

So, Your formula is PV=nRT
1.83(10.5) = n(.08206)(300.3)
n= .7797 moles Oxygen

.7797 molesO2 x 32gO2/1moleO2 = 24.95gO2

32gO2/1moleO2 is a fraction, and all the O2's, the 2 is small.
