College Chemistry Pv=nRT

Question

  What is the pressure in atm exerted by 2.48 moles of a gas in a 250.0 mL container at 58 C?

I'm so lost with this problem. can someone give me a step by step to getting the answer

i always get lost when i have to convert more than one thing.

please, if you can work this out and show each step you did, i would really appreciate it. my chem teacher runs through this so fast and I get so lost. thanks

Answer 1

Just plug in to PV=nRT and solve for P

V = 0.25 L

n = 2.48 moles

T = 331 K

R = 0.082 atm•L/mol•K

(just ask if you need to know where these came from)
