what is teh volume of one kg of air in standard atmospheric pressure and at 20 degrees Celsius? what formula do you use i cant think of anything
i used Pv=nrt but cant get it to work
please show work
i am realy stumped and need help

Use MOVED (mass over volume equals density).
Wikipedia gives the density as 1.2kg/m^3 at 20degC and at sea level.

i did chemistry long time ago but i will try
Pv=RT
P=1 atm
T=20 + 273 = 293 K
V=? u want to find
R=0.082 (constant)
so PV=RT
V=(RT)/P
V=[(0.082)(293)]/1
V= 24.3 m^3

What you need is the density of air at that pressure and temperature;
see http://en.wikipedia.org/wiki/Density_of_air
