Answer to Question #180032 in General Chemistry for Ash

Question

A nitrox to gas mixture for scuba diving contains oxygen gas at 50 ATM and nitrogen gas at 90 6:00 a.m. what is the total pressure in ATM of the scuba gas mixture

Answer 1

Dalton's law states; The total pressure exerted by a mixture of gases is equal to the sum of the pressures of each of the different gases making up the mixture, with each gas acting as if it alone was present and occupied the total volume.

P_T = PN_{2 +} PO₂

P_T= total pressure

PN₂₌ pressure of nitrogen

PO₂₌pressure of oxygen

PN₂= 0.7808 . 90 = 70.272atm

PO₂= 0.2095 . 50 = 10.475atm

P_T= (70.272 + 10.475)atm

=80.747atm
