Answer:
The temperature in Celsius is 383, 7°C
Explanation:
We use the formula PV=nRT. We convert the pressure in KPa into atm:
101,325kPa---1 atm
114kPa--------x=(114kPa x 1 atm)/101,325kPa=1, 125 atm
PV=nRT ---> T= PV/nR
T=1, 125 atm x 35, 9 L/ 0,750 mol x 0,082 l atm/K mol
T= 656, 7 K
0°C= 273K---> 656,7 -273K= <em>383,7°C</em>
Answer: The partial pressure of oxygen in the tank is 82.95 kPa.
Explanation:
According to Raoult's law, the partial pressure of a component at a given temperature is equal to the mole fraction of that component multiplied by the total pressure.
where,
= partial pressure of oxygen
= mole fraction of oxygen
= Total pressure
,
where = moles of oxygen =
= moles of Helium =
Thus the partial pressure of oxygen in the tank is 82.95 kPa.
