An unknown amount of an ideal gas is placed in a cylinder with a moving piston. The environment keeps a constant pressure 101325 Pa on the piston. You heat the gas slowly from 216 K to 221.7 K. As the teperature changes the gas performs 866 J of work.
What is the amount of gas in the cylinder?
(a) 2.14e+03 moles
(b) 4.70e-01 moles
(c) 4.82e-01 moles
(d) 1.52e+02 moles
(e) 1.83e+01 moles
