Line one: 4h atoms and 2o atoms on reactant and product side.
Line two: 4fe atoms 6o atoms on reactant and product side.
Line three: 2cl atoms, 2na atoms and 2br atoms on both the reactant and product side.
Answer:
To find the number of moles we must first calculate the molar mass( M) of Fe2O3
Molar mass = mass / number of moles
M(Fe2O3) = (55.8 ×2) + (16×3)
= 111.6 + 48
= 159.6 g/mol
number of moles = mass / molar mass
= 125g/159.6g/mol
= 0.783mol

<u><em>Answer:</em></u>
0.0735moles
<em><u>Explanation:</u></em>
Molar mass of C8H18 = 114.22852 g/mol
1 grams C8H18 is equal to 0.0087 mole.
So there are around 0.0735moles
