Answer:
mass of excessive CO = 2.55 gram
Explanation:
Fe2O3(s)+3CO(g)→2Fe(s)+3CO2(g)
moles of Fe2O3 = mass / formula mass = 22.00/(56x2+16x3)=0.1375 (mol)
moles of CO = mass / formula mass = 14.1/(16+12) = 0.503
Fe2O3 reacts completely meanwhile CO is excessive.
mass of CO reacts = 3 x nFe2O3 x M = 3 x 0.1375 x (16+12) = 11.55 gram
mass of excessive CO = initial mass - reacted mass = 14.1 - 11.55 = 2.55 gram
