**DrBob222**, Thursday, April 22, 2010 at 4:28pmC'mon. I derived an equation for you this morning. All you need to do is to substitute and solve.

P*M = (g/L)*R*T

P is pressure in atmosphere. You show it in torr. torr/760 = atm. M is molar mass. g/L is density. R is a constant = 0.08206 and T is temperature in Kelvin. Plug and chug.
