An equation for the reaction is: NiO + C = Ni + CO Calculate the percentage atom economy for the reaction to produce nickel. Relative atomic masses (Ar): C = 12 Ni = 59 Relative formula mass (Mr): NiO = 75 Give your answer to 3 significant figures.
Atom economy is a percentage value which tells you how efficient the product is in comparison to the amount of reactant used.Equation to learn: atom economy = Ar of useful product/Ar of reactantSubstitute the values your give: atom economy = 59/(75+12) = 0.67Multiply by 100 as it is a %: = 67.8% 3sf
