How to deal with dissolved ionic compounds and calculating theoretical yield with a net ionic equation

I am not sure how to calculate the theoretical yield of ClO2 when their precursors are dissolved. For example, if I mix 1 gram and 0.75 gram of sodium chlorite (NaClO2) and citrate acid (C6H8O7), respectively, technically only the ClO2- ion and H+ ion are participating in the generation of ClO2 gas (see balanced net ionic equation below). In this case, would I need to "spit" the 1 gram of sodium chlorite based on molar ratios of Na and ClO2 and do the same for citric acid but only consider the 3 ionizable hydrogen atoms of citric acid?


Net ionic equation for produced of ClO2 gas via NaClO2 and C6H8O7:


4ClO2-(aq) + 2H+ (aq) ClO2 (gas) + ClO3- (aq) + Cl- (aq) + H2O
