If 10.5 mol of an ideal gas occupies 15.5 L at 19.00 °C, what is the pressure of the gas?

OpenStudy (anonymous):

Pv=nrt P(15.5L)=10.5mol(.0821)(19+273)

I got the numbers from knowing the constant, which you have to memorize. r=.0821, and since i'm a horrible chemistry student I don't know the units off the top of my head. But this is when temperature is in kelvin and volume is in L and pressure is in atm.

Also to convert from degrees celsius to kelvin, its whatever you have +273.
