How many mols of an ideal gas are there in a 3.0 L container maintained at 45.0 °C and 2.5 of pressure?

Moles of an ideal gas are : 0.288

In general, the gas equation can be written

where

P = pressure, atm

V = volume, liter

n = number of moles

R = gas constant = 0.082 l.atm / mol K

T = temperature, Kelvin

Volume=V=3 L

T = 45°C+273=318 K

P = 2.5 atm

o conteúdo de calor de um sistema é igual à entalpia apenas para um sistema que é constante
