Chapter 10, Problem 67

A piece of dry ice (solid carbon dioxide) with a mass of 5.50 g is placed in a 10.0-L vessel that already contains air at 705 torr and 24°C. After the carbon dioxide has totally sublimed, what is the partial pressure of the resultant CO2 gas, and the total pressure in the container, at 24°C?

Video transcript

Hey everyone we have a 15 liter gas canister containing Xenon gas. 100 tour 60°C is added With 10.5 g of solid iodine. We're going to assume that all iodine sublime is to a gas and calculate the partial pressure of I. D. And gas and the total pressure inside the canister. When he's the first one in the malls of iodine. Then we can plug it into the ideal gas wall to find the partial pressure of iodine. You have 10.5 grams of iodine and in one more of iodine you have the molar mass Which is 126 .90.4 grams. And this gives us 0.08 27 malls of iodine. Then I can put this into the ideal gas law which is P. B. Equals and R. T. And we can rearrange this is all for the pressure which is N. R. T. Divided by B. So we're looking for the pressure Number of Malls is 0.08. She's seven. Our value is 0.08 206 Leader sounds atmosphere. What about malls? I'm Calvin. The temperature is 60°C. We need to convert this to Calvin. We're gonna add 273 115. Get 333 115 Kelvin In the volume is 15 L. So if you plug this in we're gonna get pete People. 27 malls Time. to a six Leader sam's atmosphere a lot. About Malls times Calvin Times 333 .15 Kelvin. You got about 15 l definitely pressure. We're gonna get 0.151 atmosphere. Now I need to find the total pressure. Using a pressure pressure of I. D. And gas. We call that the total pressure. It's a pressure of gas one that's the pressure of gas too. So we're giving the partial pressure of xenon gas and torque. We're gonna need to convert this to atmosphere. We have 800 tour, We have 760 tour in one atmosphere. Just give us 1.05 atmosphere for the total pressure. The 1.05 atmosphere. 0.151 atmosphere. The total pressure It goes 1. atmosphere. Thanks for watching my video and I hope it was helpful.
