Calculate the density of ammonia (NH(3))...

Calculate the density of ammonia `(NH_(3))` in grams per liter `(g L^(-1))` at `752 mm Hg` and `55^(@) C`.
Strategy : convert the pressure to atmosphere and temperature to Kelvin . Then use Eq.(5.22) to calculate the density of ammonia gas.

Text Solution

Verified by Experts

`p = (752 mm Hg) xx ((1 "atm")/(760 mm Hg))`
`= 0.989 "atm"`
`T = 273 + 55 = 328 K`
Using Eq. (5.22), we have
`d = (pM)/(RT) = ((0.989 "atm")(17.03 g mol^(-1)))/((0.0821 ("L atm")/("K mol")) (328 K))`
`= 0.626 gL^(-1)s`
