How many joules of translational kinetic energy is associated with 4 g

1.	How many joules of translational kinetic energy is associated with 4 grams of methane at 27°c?
Answer» Number of moles of methane = weight of methane ➗ GMW =4/16 = 1/4Kinetic energy is given as (K. E.); K. E = 3/2 nrt; = 3/2 x1/4 x 8.314 x 300 = 935 joule
