a mixture of oxygen, hydrogen, carbon dioxide and methane gases have a total pressure of 1.3 ATM. if the partial pressure of hydrogen is 2.4 PSI, the partial pressure of carbon dioxide is 110 torr can the partial pressure of methane is 0.22 ATM, how many mmhg does oxygen exert?
According to Dalton's law total pressure of gas is equal to sum of partial pressure exerted by each gas
Ptotal = Poxygen + Phydrogen + Pcabon dioxide + Pmethane
Ptotal =
1.3atm to mmHg
1 atm = 760 mmHg
= 1.3atm/1atm x 760mmHg = 987.999mmHg
PH2 =
2.4 PSI to mmHg
2.4PSI/1PSI x 51.714mmHg = 124.115 mmHg
PCO2 =
110 torr to mmHg
109.999 mmHg
PCH4 =
0.22atm to mmHg
0.22atm/1atm x 760 mmHg = 167.199mmHg
Poxygen = Ptotal – (PH2 + PCO2 + PCH4)
= 987.999 – (124.115 + 109.999 +167.199)
= 987.999 - 401.313
= 586.686 mmHg
Oxygen exert 586.686 mmHg
