A flask of volume 9.1 liters contains 5.0g of hydrogen, 0.55moles of oxygen, and sufficient argon so that the partial pressureof argon is 2.20 atm. The temperature is 136 c.
a) What is the density of the mixture in the flask?
b) Suppose that a spark is passed through the flask so that thefollowing reaction occurs until one reactant is entirely used up:2H2(g) + O2(g) -> 2H2O(g)
What will the pressure be when the temperture returns to 136C?
