How many joules of translational kinetic...

How many joules of translational kinetic energy is associated with 4 grams of methane at `27^@C`?

Text Solution

Verified by Experts

Number of moles of methane ` = ("weight of methane")/("GMW") = (4)/(16) = (1)/(4)`
Kinetic energy is given as (K.E.)` = (3)/(2)nRT = (3)/(2) xx(1)/(4) xx 8.314 xx 300 = 935` joule
