What is the density of ammonia (nh3) at 293 k and 0.913 atm?

Answer : The density of ammonia is 0.6464 g/L.

Solution : Given,

Temperature of ammonia = 293 K

Pressure of ammonia = 0.913 atm

Molar mass of ammonia = 17.031 g/mole

By using ideal gas law,

where,

P = pressure of gas

V = volume of gas

n = number of moles

T = temperature of gas

R = Gas constant = 0.0821 Latm/mole/K

= Density

and

Now put all given values in ideal gas law, we get

Therefore, the density of ammonia is 0.6464 g/L.
