1a) a 250 ml container of co2 exerting a pressure of 1.00 atm is connected through a valve to a 500 ml container of o2 exerting a pressure of 2.00 atm. when the valve is opened, the gases mix, forming a 750 ml mixture of co2 and o2. what is the total pressure of this mixture?
1b) each molecule of hemoglobin combines with four molecule of oxygen in order to transport oxygen throughout the body. it is observed that 1.51 g of hemoglobin combines with 2.30 ml of o 2 at 37 °c and 743 torr. what is the molar mass of hemoglobin?

the correct answer is b. a strong acid completely dissociates to its ions when dissolved in water. completely dissociates to and ions. a is incorrect because does not fully ionize to and ions and some remain as the compound . c and d are incorrect because, and do not fall into the category of bronsted lowry acids. a bronsted lowry acid is a proton donor and since both molecules do not have a proton to donate they are not bronsted lowry acids. likewise,   if we use the lewis acid definition, they cannot be acids. a lewis acid is an electron pair acceptor. both and have a complete octet so can not accept any electrons which disqualifies them as acids.
