MISSED THIS? Watch KCV: Mixtures of Gases and Partial Pressures, IWE: Total Pressure and Partial Pressures; Read Section 6.6. You can click on the Review link to access the section in your eText. A gas mixture contains each of the following gases at the indicated partial pressures: N₂, 129 torr ; O2, 287 torr; and He, 172 torr. ▼ ✔ Correct According to Dalton's law of partial pressures, the total pressure of a mixture of gases is the sum of the pressures of the individual gases in the mixture. Use the given partial pressures of each of the gases to calculate the total pressure. PTotal Part B = ▶ = PN₂ + PO₂ + PHe 129 torr + 287 torr +172 torr = 588 torr What mass of each gas is present in a 1.00L sample of this mixture at 25.0°C?

Organic Functional Groups Identifying positions labeled with Greek letters in acids and derivatives If possible, replace an H atom on the a carbon of the molecule in the drawing area with a methyl group substituent, and replace an H atom on the ß carbon with a hydroxyl group substituent. If one of the substituents can't be added for any reason, just don't add it. If neither substituent can be added, check the box under the drawing area. HO Oneither substituent can be added. OH 0/5 X
