0.161 mols.

Balance the equation first

2Fe + O2 •••••> 2FeO

Find the molar masses of the compound

2(56) + 2(16) •••••> 2(56+16)

112g + 32g •••••> 144g

Fe reacting with O2

112g of Fe reacting with 32g of O2

18g of Fe reacting with x

x= 32×18/112

x= 5.143g

Amount= mass/ molar mass

Amount= 5.143g/32g

Amount= 0.161mls
