L - isomer is considered as the Enantiomer of d - isomer and since the d-isomer optical rotation is + 13.5° so the optical rotation of l-isomer will be the same degree but with opposite sign which equal to - 13.5°

So the degree of rotation of racemic mixture will equal 0°

- This is because racemic mixture contains equal amount of both enantiomers
