A scientist 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 mc016-1.jpg. 0.27 atm 0.36 atm 0.54 atm 0.90 atm
If you add the two known partial pressures and subtract it from the known total pressure you get your answer. The answer is 0.36 atm.
