Question: 1 l atm is how many joules?
Answer: To change from units of L atm to Joules, multiply the gas constant 8.31447 J/mol K and divide by the gas constant 0.08206 L atm/mol K. This is the same as multiplying by 1/1, since the gas constants are the same value with different units. If you do this, you will notice that 1 L atm = 101.325 J.
