What is the density of nh3 at 800 torr and 25 c

Density ca n be calculated as follows:

d=P (FW) / RT

d = density, FW formula weight which is 17.031 g / mol

R = gas constant 0.082 6 L atm K-1 mol-1

T = temperature, 25 C or 298 K

P = pressure 800 torr or 1.053 atm

Therefore

d=P (FW) / RT

= 1.053 * 17.031 / 0.08206 * 298

= 0.733 g / L
