A 18.0 L gas cylinder has been filled with 5.00 moles of gas. You measure the pressure to be 4.30 atm.? What is the temperature inside the tank?
Answer
A particular of gas is described by its pressure, volume, temperature, and the number of moles. Knowledge of any of three of these properties is enough to completely define the state of the gas, since the fourth properties can then determine from the equation of ideal gas law.
PV = nRT
R is universal gas constant 0.08206 L.amt/K.mol
P is the pressure in atm
V is the volume in Liter
n is the moles
T is temperature in Kelvin
4.30x 18.0 L = 5 x 0.08206 x T
T = 188.6 K
