There were a few question on my homework that I wasn't sure how to do
What is the average velocity of the argon atoms in the gas phase at 75°F?
If an unknown gas diffuses 1.41 times faster than oxygen gas, what is its molar mass?
A hydrocarbon gas contains 81.71% carbon and 18.29% hydrogen, by mass. At STP, 4.20 L of the gas has a mass of 8.27 g. What is the molecular formula for the compound?
Thanks! =)
