Answer:
Therefore, there are 4.47 moles of propane present at STP in a volume of 65.0 L
Step-by-step explanation:
First, we need to calculate the number of moles of propane present at STP. At STP, the temperature is 273 K and the pressure is 1 atm.
Using the Ideal Gas Law, we can calculate the number of moles of propane present in the given volume.
PV = nRT
n = 4.47 mol
Therefore, there are 4.47 moles of propane present at STP in a volume of 65.0 L
