mole%kat=100*nkat/n, where nkat is the amount of catalyst and n is the total amount of the substance in the system!
Hi Sagar, see the attached photo. I guess this is what you wanted.
Thanks
Just multiply the mole of reactant taken with 1%(0.01), you will get moles of catalyst taken.
x mol% of catalyst = (no. of moles of catalyst X 100)/(number of moles of catalyst + number of mole of limiting reagent).
mol% of catalyst
(no. of moles of catalyst)/(number of moles of catalyst + number of mole of limiting reagent) X 100
Check this Web application. Its fast, accurate and free.

Say you need weight of 3 mol% catalyst:
Calculation:
Mass of 1 mol% catalyst in grams = (no. of moles of limiting regent) x (molecular weight of the catalyst in gram) / 100
eg. if 5 mM (i.e. 0.005 M) of the limiting reagent is being used, and the molecular weight of the catalyst is 220 g/mol, then 1 mol% of the catalyst would be
(0.005 x 220) / 100 = 0.011 g
Therefore, 3 mol% catalyst would be 3 x 0.011 g = 0.033 g = 33 mg
