Determine the mass number of the element?

A mass of 25.2 g of an element is known to contain 6.77x 1023atoms. What is the mass number of the element?

I thought it would be N/Na where Na is equal to avogadro's number 6.022x10^23, and then 25.2 divided by the answer above. (the units being u) edugen website will not accept any answer I try out in there.

Please Help!
