Calculate the number of moles of O atoms in 13.27 g Mn(NO3)2.
Hi I did this question and it seemed pretty easy but there is this online assignment I am doing it for and it says I am not getting the right answer.
Please can someone try it and see if they get what i do, or tell me what I am doing wrong
My Solution:
mass (13.27g) x
1 mole
------------------------------- x
MM of Mn(NO3)2 (178.96g/mol)
6 atoms of O
----------------- = .4449 mol
1 mole
When i submit my answer it says Incorrect!
I don't understand what's wrong with that
