calculate the number of moles of moles of iron prepared
mole= mass/RFM
RFM of iron is =56 g/ mol
moles of iron prepared is therefore 112g /56g/mol=2moles
by use of reacting ratio between Fe2O3 to Fe that is 1:2 therefore moles of Fe2O3 used is (1x2)/2+1 mole
mass of Fe2O3=RFM x number of moles
RFM of Fe2O3=160g/mol
mass= 1 mole x 160 g/.mol=160g (D)
mole= mass/RFM
RFM of iron is =56 g/ mol
moles of iron prepared is therefore 112g /56g/mol=2moles
by use of reacting ratio between Fe2O3 to Fe that is 1:2 therefore moles of Fe2O3 used is (1x2)/2+1 mole
mass of Fe2O3=RFM x number of moles
RFM of Fe2O3=160g/mol
mass= 1 mole x 160 g/.mol=160g (D)
