gas law question (answer included; review please)
« on: October 18, 2008, 12:48:36 AM »
What is the pressure in a 2.50 L tank of CH4 gas containing 60 g of gas measured at 12*C?

PV = nRT

P = nRT
       V

= (62.4mm/molK)(60g of CH4)(273+12)K
                                 2.50L

hey!

n is the mole of CH4 not mass, so you need to covert. As for the molar gas constant, check the units but most probably is 8.31.
