@foxhunter98  Then how did you answer my question??

frostbite · Answer

I 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):
$$\sum_{}^{}m(reactants)=\sum_{}^{}m(products+waist)$$
