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 (p_t = p_1+p_2 + p_3+cdots+p_n). 0.27 atm 0.36 atm 0.54 atm 0.90 atm

Answer

Explanation:

Step1: Identify given values

$P_T = 0.90$ atm, $P_1=0.26$ atm, $P_2 = 0.28$ atm

Step2: Apply partial - pressure formula

$P_T=P_1 + P_2+P_3$. We want to find $P_3$. Rearranging gives $P_3=P_T-(P_1 + P_2)$.

Step3: Calculate $P_3$

$P_3=0.90-(0.26 + 0.28)=0.90 - 0.54=0.36$ atm

Answer:

0.36 atm
