Question

The Henry's law constant for CO2 in water at 25 °C is 3.1x10^-2 M atm-1. (a) What is the soubility of CO2 in water at this temperature if the soltuion is in contact with air at normal atmospheric pressure?

Hello everyone today. We have been given the following problem and asked to solve for it. It does calculate this eligibility of helium in water at 30°C and standard atmospheric pressure. If Henry's law constant at this temperature is a 3.7 times 10 to the negative fourth molars per atmospheres. It then goes tells that the mole fraction of helium in the air is 5.24 times 10 to the negative six atmospheres. So the overall idea is that we want to calculate the partial pressure of helium. So we're going to review that as P and then subscript H. E. We're then going to say that we're gonna take our X value, we're gonna take helium. Then we're gonna have our pressure in atmospheres. And so we plug our numbers and we get our five Times 10 to the -6. And this is our mole fraction, that's what X is. And then we take our one atmospheres and that will give us a value of 5.24 times 10 to the negative six atmospheres. Next, we want to calculate this eligibility overall. So sorry, ability of helium will be abbreviated as such. We're going to equal that to the Henry. Henry's gas constant, which is k times our partial pressure of helium. And so we're going to plug in that constant. That was given to us that 3.7 times 10 to the negative 4th moller over atmospheres. And then we're going to multiply this number by the partial pressure that was given to us that we sold for which is 5.24 times 10 to the negative six atmospheres. Our units are going to cancel out, and we are going to be left with a solid ability of 1.94 times 10 to the negative ninth polarity. As our final answer, I hope this helped, and until next time.
