PV=nRT
You know P, R, and T.
Calculate the Volume for 1 mole (2.016 gram).
Calculate V and divide the mass (2.016) by the V to get density.

The tricky part is the conversions. 760 mm Hg (1 atmosphere) = 14.7 lbs/in^2. 19.0 deg C = 292.15 deg K.

ρ = (2.016 g/22.4L)(293/292)(1670/14.7)
ρ = 10.260 g/L
