So this problem gets us a reaction. Um, and we're collecting high shin gas, but we're doing it through, um, water displacement. So we're gonna have water vapor as well. So it gives us the total volume, the total temperature, the gentle pressure, um, and the partial pressure of water vapour at 30 degrees Celsius, the temperature of the system. And we need to find the partial pressure of hydrogen gas, the moles of hydrogen gas produced and the grams of sink that would produce that many angles of hard hitting us. So first we need to used also a partial pressures and find the partial pressure of hydrogen gas. So partial pressure. Eso pressure total is equal to the portal pressure of H 20 plus the partial pressure of age to so 1.32 And we need to convert 32 tourist a team. So to do that, we would divide by 760 Um, and because that's equal to one HTM and then we would get that value to be 0.0 for 21 HTM, plus the partial pressure. Parchin. If we rearrange that equation, will get the partial pressure of hydrogen gas to be equal to 0.989 HTM. So that's our first answer and will need to use that for finding the moles of hydrogen gas. So to do that will dio the ideal Gasol, which is P b equals NRT and when you to use that we're solving for the moles of art you got. So I need to use the specific values for hygiene, for pressure for volume for temptress So overpressure will use the same exact one we just saw for so n is equal to P B over rt. So is Europe When 989 times the volume which we were told the volume of hydrogen gas is 240 milliliters. So that's equal 2.24 leaders and then divided by R value 0.8 to 1 with these specific units and the temperature of the system is 30 degrees. So the temperature of hydrogen gas 30 degrees. So add 273 to get this value into Kelvin and we get 303 Copan And then if we plug these values into our calculator, we get the moles is equal to 0.954 nos a Haitian gas and then, when you find the grams of sink that would produce that amount of high drink us. So let's look at the equation. We see one sink forms one hydrogen gas, so they have a 1 to 1 molar ratio. So 0.954 moles of hydrogen gas. So for one more of hydrogen gas, there's one more of zinc and so and one more zinc. There is 65 grams of sink, and if we plug this into our calculator will get 0.62 grams of sink, and so these are our three answers.
