The temperature of the sample in degrees celsius is 238.89ºC.
The ideal gas equation can be rewritten to demonstrate that the pressure of a sample of gas is directly proportional to the number of moles of the gas present if volume and temperature are held constant:
deal Gas Law
PV = nRT
P = pressure = 2.10 atm
V = volume = 77.27 L
n = moles = 3.86
R = gas constant = 0.0821 Latm/Kmol
T = temperature in Kelvin = ?
Solving for T:
T = PV/nR = (2.10)(77.27)/(3.86)(0.0821)
T = 512.04 K
To convert to ºC, subtract 273.15K
T = 512.04 - 273.15 = 238.89ºC
