(2 equations) Moles = mass / Mr Mass = moles x Mr 1 of 7 What is the Equation that links mass, volume and concentration? Concentration = mass / volume 2 of 7 What is the equation that finds conc. in mol/dm^3? (Hint links conc. moles and volume) Conc = moles / volume 3 of 7 What are 2 other conc equations? 1) conc. = mass of solute / vol. of solvent 2) conc. = no. of moles of solute / vol of solvent 4 of 7 2 equations that link vol of gas, 24 and moles? Vol. of gas = moles x 24 Moles = vol. of gas / 24 5 of 7 What is the equation for Atom Economy? A.E = Mr of Desired products / Me of all the reactants x 100 6 of 7 What is the equation for % yield? Actual amount you got / highest theoretical mass x 100 7 of 7
