Jeff and Jill canoeing. While reaching for the duck feed, boat tipped Jeff and Jill beyond this their inflatable preserver and then she hung up. As they wait for the rescue squad, they calculate how much nitrogen is in every life preserver. They estimate that the volume L 17, atmat pressurized to 1.2 25 ◦ C. The air used for inflation 80% nitrogen and 20 vol% oxygen by volume. Enter the amount of nitrogen gas. Answer in grams
Lil'Asia, Let's assume ideal gas behavior PV = nRT n = PV / RT = (1.2 atm) * (17 L) / ((0.0821 L atm / mol K) * (273.15 + 25)) = 0.833 mol If 80% like N2, then N2 moles = 0.80 * 0.833 = 0.667 mol N2 = 0.667 grams moles * 28.02 g / mol = 18.7 g = 19 (two sig figs) Hope that helped!
