Question

Problem 8.68 A nitrox II gas mixture for scuba diving contains oxygen gas at 55 atm and nitrogen gas at 98 atm. What is the total pressure, in torrs, of the scuba gas mixture? (Express in 3 significant numbers) Problem 8.68 A nitrox II gas mixture for scuba diving contains oxygen gas at 55 atm and nitrogen gas at 98 atm.

What is the total pressure, in torrs, of the scuba gas mixture? (Express in 3 significant numbers)

Explanation / Answer

partial presuure of O2 = 55 atm

partial presuure of N2 = 98 atm

total pressure = partial presuure of O2 + partial presuure of N2 = (55+98) atm =153 atm

because 1atm = 760torr

therefore , 153 atm = 153 x 760 torr =116280 torr. =1.16 x 105 torr
