What Law do I use?

Think of the equations you have learned and which variables you have been given. It helps to keep a list of them in front of you so you can quickly figure it out. Then just plug in. If you have P, V, mass, and T....you're going to use PV=nRT...just solve for P
PV=nRT is an equation you're going to want to just memorize...you'll be using it a lot.. 
Oh the Ideal Law? Thank you so much!!

no problem :)
