Is this sentence correct?

Sorry, this is the sentence :
It takes me much time of answering students questions.

Thanks!

AnonymousIt takes me much of answering students questions.

No, that doesn't work, and it's not clear what you mean. Did you have in mind something like:
I spend a lot of time answering students' questions.
I spend much of my time answering students' questions.
Answering students' questions takes much of my time.

Thank you for you examples!
I've got the apostrophe correction.
Yes, this is exactly what I meant but I missed time in my sentence. In my understanding much expects an object but a lot of doesn't. Can we then say:

It takes me a lot of time answering students' questions.


Thanks!

I saw your correction after I posted, but I would have given more or less the same answer if I had seen it first
