Best ResponseYou've already chosen the best response.1I sure can... Lets consider we have a reaction called 2 A +9 B > 5 C + 2 D. To say this in words: 2 moles of A react with 9 moles of B to create 5 moles of C and 2 moles of D. So for the calculations to work out we need to say (for a reaction assuming that all the reactants are converted): \[\sum_{}^{}m(reactants)=\sum_{}^{}m(products+waist)\]
