Oxygen gas is collected at a pressure of 123 kPa in a container which has a volume of 10.0L. What temperature must be maintained
on 0.500 miles of gas in order to maintain this pressure? Express the temperature in degrees Celsius?
2 answers:
Given:
P = 123 kPa
V = 10.0 L
n = 0.500 moles
T = ?
Assume that the gas ideally, thus, we can use the ideal gas equation:
PV = nRT
where R = 0.0821 L atm/mol K
123 kPa * 1 atm/101.325 kPa * 10.0 L = 0.500 moles * 0.0821 Latm/molK * T
solve for T
T = 295.72 K<span />
Answer:
23C
Explanation:
As oxygen is in a gaseous state, and with the data that gives us the problem we must use the equation of ideal gases

P= pression
V= volumen
n= moles
r= constant of ideal gases
T= temperature
data:
Pression: 123 KPa
Volumen: 10.0L
moles: 0.5 moles
constant of ideal gases: 
we transform the liters to cubic meters:

we clear the temperature and replace the data

The temperature is 296 K but we have to expressed in Celsius
