Question

_{Partial pressures The scene below depicts a mixture of four gases. (1) Which gas has the lowest partial pressure? black (2) Which gas has the highest partial pressure? green - (3) If the total pressure is 1.57 atm, the partial pressure of the purple gas is atm. (Report as a number to two decimal places.) (4) When the total pressure of a mixture of gases is lowered, the partial pressures of individual gases is also reduced. Suppose you are in an airplane flying at an altitude of 5,000 ft. where the external air pressure is 0.83 atm, and the cabin suddenly depressurized. If oxygen gas constitutes 21 mol% of the atmosphere, what is the partial pressure of oxygen that you encounter? atm. Do you think you will survive if your body requires at least 0.15 atm O, for your blood to be sufficiently oxygenated?}

Answer 1

duy Daltons love of poetial focawee of mixture of Jesus P = P, & Pzt Bez t – – so. Pn= P, X , where Pn= Portical pressuy = Pnd Na Xn= mole frection, Solution & Let we assumed. I ball = 1 mole. So. moles of green = 5 moles of black & 3 moles of purpel = 4 males of yellaue = 1 we know, In a la nnus moles of gas 80)!) black gas has the lowest poctial pressures 2) geen gas has the higest partial pressures 3) moles frection of pwplec moles of pueble x purple = 573tuty 16 - 8o. partial pressure = Pq X Xpurple = 1.57 atm X 0.25 4 = 4 -0.25

Purple = 0.3925 atm 3) set we have 100 mols of total gas. So. males of Og = 21% of 100 moles = 21x100mal = almal 100 mole frection of Og= moles of O2 = 21 Totalmales 20.21 mal Po = Pp XXoz Po = 0.83 × 0.21 = 0. 1743 atm Poo = 001793 at - " 001743 ) 0.15 So, we can survive.
