Chemistry reactions and stuff

The question:

""""""
LiOH can be produced by the following formula:

Li3N + 3 H2O -> 3 LiOH + NH3

How many mol of LiOH is produced if you mix 7 grams of Li3N to a large amount of water?
"""""""

My solution:

7 grams of Li3N would be 0,44 mol

so if
1 mol of Li3N = 3 mol LiOH
then
0,44 mol of Li3N = 1,32 mol LiOH

Wrong or right? Win or fail? If wrong/fail then I would appreciate it if someone showed me the right way to solve this. Thanks.
