Ascientist is examining a mixture of nitrogen, hydrogen, and ammonia. the individual pressures that are exerted by nitrogen
and hydrogen are 0.26 atm and 0.28 atm, respectively. if the total pressure is 0.90 atm, what is the partial pressure of
ammonia?
use p7= pa + p2+p3++p
o 0.27 atm
o 0.36 atm
o 0.54 atm
o 0.90 atm

Option B

0.36 atm

Explanation:

Pt= P1+P2+P3

where Pt is the total pressure, P1, P2, P3 are pressure for respective gases

Substituting 0.9 atm for Pt, 0.26 for P1 and 0.28 for P2 then

0.9 at= 0.26 atm + 0.28 atm + P3

P3= 0.9-0.26-0.28= 0.36 atm

Therefore, the partial pressure of ammonia is 0.36 atm
