Surfing For How Many Molecules Of Air Are In A Room?

Paul asks…Moles in a room help..?Estimate the number of air molecules in a room of length 4.0 m, width 1.0 m, and height 2.0 m. Assume the temperature is 20°C. How many moles does that correspond to

So far i got that V = 4*2*1 *R(1000L/m^3) / .82 * 293.15

= 332.8 moles * 6.023 x 10^23
Any help?Nancy answers:If it involves having Avogadro's Number memorized, you'd better move this to the chemistry section. :)Helen asks…chemistry ideal gas law?How many air molecules are in a12.5 x12.0
