Answer: 617.35 °C
Explanation:
Using the ideal gas law,
PV = nRT
P = Pressure in (atm or pascal)
V = Volume in (litres or cubic metres)
n = number of moles.
R = Gas constant in (0.0821L .atm/mol.K or 8.314J/mol/K)
T = Temperature in degree Kelvin or Celsius.
PV = nRT
P = 2.91atm, V= 78.13L , n= 3.11
R = 0.0821L .atm/mol.K
T = ?
T = 2.91 x 78.13 / 3.11 x 0.0821 = 227.3583/ 0.255331 = 890.5 K
Converting from Kelvin to Celsius, using: °C = K - 273.15
= 890.5 - 273.15
°C = 617.35
