The temperature in K is 503.84 K
calculation
The temperature in K is calculated using the ideal gas equation.
That is Pv = nRT
where
p(pressure)= 6.7 atm
V( volume) = 14.2 l
n( number of moles)= 2.3 moles
R( gas constant) = 0.0821 atm.L/K.mol
T( temperature)= ? K
make T the subject of the formula by diving both side of equation by nR
T =PV/nR
T =[(6.7 atm x 14.2 l) / (2.3 moles x0.0821 atm.l/k.mol)] = 503.84 K
