<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
2/1.01=1.980=2
32.7/32.07=1.020=1
65.3/16.00=3.969=4
H2SO4. oxygen is 1
2Nz + H2 = 2NHz
2KCIO3 = 2KCI + 3O2
