Only 75.23 moles are OK
I think I need to multiply 75.23 with 7.4/100. but I'm not sure.

Have you ever heard of significant figures?
Question is poorly formulated in this aspect, it asks for using atomic masses to 3 decimal points, yet gives 6Li abundance to only two sigfigs.That being said, the number is OK, it is just a matter of a correct representation of its uncertainty.
The answer will be 5.567?
