Following the atomic mass of each of these atoms, we have 1 Fe atom with 56 amu, 3 N atoms with 14 each, and 9 O atoms with atomic mass 16. Adding these together, we get 56 + 42 + 144 = 144 + 98 = 242. Your answer is (4) 242 g/mol
Hydrogen sulfide

The diatomic molecule that is formed when two atoms share six electrons is N2.
The atomic number of nitrogen is 7 and its electronic configuration is 2,5. This implies that, nitrogen has 5 electrons in its outermost shell. To attain the octet structure, it needs 3 electrons more. To form a diatomic molecule, two nitrogen atoms come together and each donate three electrons, which are equally shared between the two, thus, each ends up having 8 electrons in its outermost shell.
<h3><u>Answer;</u></h3>
160 g
<h3><u>Explanation;</u></h3>
1 mole of a compound contains a mass equivalent to the relative formula mass of that particular compound.
the formula of iron oxide is Fe2O3
R.A.M of Iron = 56 , while that of oxygen is 16
RFM = (56 ×2) + (16 ×3)
= 112 + 48
= 160
Therefore, 1 mole of Iron oxide contains 160 g
