Answer:
<u>399.88</u>
Explanation:
The molar mass is just the number of total mass of each atom of each element.
2 - Fe = (55.845 x 2) = 111.69
3 - S = (32.06 x 3) = 96.18
12 - O = (15.999 x 12) = 191.988
For oxygen, it's being added 12 times because there is 4 in the compound times the 3 on the outside.
Now, add all of them and you have your answer!
Answer:
It's easier to lose 3 electrons than gain 5 electrons to fill the outer shell. Therefore aluminum atoms will lose 3 electrons so it takes on a +3 charge when it becomes ion. Specifically it would be a cation due to the positive charge. Aluminum can just lose one to form a positively charged ion
