At 414 K, Kp = 18 for the reaction H2(g) + I2(g) ⇌ 2HI(g). Initially, 74.7 g of HI (MW = 127.912 g/mol) is injected into an evacuated 5.66-L rigid cylinder at 414 K. What is the total pressure inside the cylinder when the system comes to equilibrium? R = 0.0820568 L·atm/mol·K. Report your answer to three significant figures.
