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
