im having a problem with some questions! I don't really know how to do them so if i could have some help i would gladly appreciate it!

How many grams of N2 occupy 6.6 L at a temperature of 355 K and pressure of 103 kPa?

how do i do and solve this?!?

Use this equation
PV =nRT to get number of moles .Tke care of the units of P and convert it in atm and than use
R = 0.0821   L atm K−1 mol−1
Convert moles into mass
mass = moles x molar mass
