Calculate the density of `NH_(3)` at `30^(@)C` and 5 atm pressure.

Options

A. `3.03 g //`litres
B. 3.82 g `//` litres
C. `3.42 g //` litres
D. `4.42 g //` litres.

Answer

C

Explanation

PV =nRT, or `PV=( m )/( M) RT` or `P = ( m)/( V ) xx ( RT )/( M ) `or `P = d xx( RT )/( M ) `
` d = MP //RT , d= ( 17 xx5)/( 0.082 xx 303) = 3.42 g//` litres
