anonymous · Answer

you can use the ideal gas equation for this one...
$$PV = \left( m/MM \right) RT$$
where:
m-mass of the unknown gas
P,V,T- given conditions at stp
R-universal gas constant

then you can solve for the MM of the unknown gas and from the molar mass, u can determine the empirical formua
