C : Mole Ratio
here is the reason whenever we start giving answer if any question of stoichiometry problem ( how much reacted produced yield % ) these are steps
1 . write the balanced equation
2 Convert everything given to moles
3. determine limiting reagent '
4. Convert mole limiting reagent to mole
other species
5. convert moles to mass
6. %yield = ( actual mass / theoretical mass ) * 100%
Coefficient of balanced equation are mole ratio
