What mass of neon gas is required to fill a 5.00-L container to
a pressure of 1.02 atm at 25 °C?

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:
