Answer:

103.842 g/mol

Explanation:

The molar mass of a compound can be calculated by adding the elements and their atomic masses (use a periodic table)

Fe: 55.845

O: 15.999 (there are three oxygens)

55.845 + 15.999*3 = 103.842

MgX2 Very low density Highly reactive Diatomic Using the periodic table, determine which element these characteristics MOST LIKE
photoshop1234 [79]
Oxygen, fluorine and iodine are diatomic elements. Flourine is more reactive than the other two because it is the closest away to filling its outer layer of electrons and becoming stable like a noble gas.
