Question

A sample of ammonia gas occupies 2.65 L when measured at 28 degrees celsius and 1.38 atm. What is the density of the ammonia under these conditions?

Please help, I'm not sure which formula to use! Thank you.

I would use this one.
P*molar mass = density*RT
density will be in g/L.

Thank you! Did you get 1.26 g/L
DrBob222
No. The answer is less than 1 g/L.

0.951g/L

I obtained 0.9498 which I would round to 0.950 g/L. I used 17 for the molar mass and 0.08206 for R.
