Calculate the total kinetic energy in joules, of the molecules in 8 gm of methane at `27^(@0C` -

A

1770.5 Joule

B

1870. 6 joule

C

1970. 5 joule

D

1670.5 joule

Text Solution

Verified by Experts

The correct Answer is:
B
`E_(K)` ( For 1 mole ) `= ( 3)/( 2) RT = 3741 `Joule
Total energy of 8 gm of methane
`= ( 1)/( 2) `mole of methane
`= ( 3741 )/( 2) = 1870.5 `Joule
