1.9 mol of gas at a temperature of 180 C fills a 3.4 L container.
What is the gas pressure?
Never been good at physics or mol stuff, how do you set it up?

Use the ideal gas formula:
P V = n R T
T has to be in Kelvin degrees, which would be 93 K.
n = 1.9 moles
V = 3.4 liters
R = 0.0821 atm*L/mole*K is the "gas constant"
Solve for P in atmospheres

Thank you! That really helped!

You're welcome. Remembering the formula is easy, but I always have to look up the value of R.
