i have been trying for a few hours now to solve this, but i missed tis day in class and my mind wont wrap around the concept. can someoneplease help?? How many moles of Neon are in a 25mL container at STP?
1 mole of an ideal gas occupies 22.4 L at STP.
Therefore, 0.025L/22.4L = ?? moles.
You may also use the gas law of PV = nRT
Plug in 1 atm for P, 273 for T (those are STP) and 0.08205 for R and solve for n. You should get the same answer either way.
