Answer:
.96875 moles
Explanation:
22.4 liters per mole at STP for a gas
21.7 / 22.4 = .96875 moles
Answer:

Explanation:
Hello,
In this case, by using the ideal gas equation:

We can compute the mass of neon gas at the given conditions by firstly computing the moles and also considering the temperature in kelvins (298K):

Finally, by using the atomic mass of neon gas (20.18g/mol) we compute the required mass to fill the 5.00-L container:

Best regards.
