The total blood volume of an infant is approximately 300ml while that of an adult is approximately 4.7l. for a normal healthy individual the po, = 80mmhg for arterial blood and 40mmhg for venous blood. oxygen saturation is approximately 20ml per 100 ml of blood. given that 70% of the total blood volume is in the veins at any given time, calculate the grams of oxygen dissolved in an infant and in an adult using the ideal gas law. b. make the same calculation using the van der waal's equation of state here is something to keep in mind while you are working on the pv diagram homework. when you calculate work by using the gas constant, r, you will get a result in j. make sure that you report that in kj. when you calculate work from p*(v2 - v1), you will get a result in l*atm. you need to convert this to kj. to do that use a ratio of the two r's. this will give you a conversion factor between l*atm and j.
