What is the mole ratio of the reactants in a tube containing:

Pb(NO3) 22.0mL 0.5 mol
NaI 16.0mL 0.5 mol

Correction : Pb(NO3)2 2.0mL

You didn't write all of the information and/or it's unclear what you want done.

To determine the mole ratio of the reactants in a chemical reaction, we need to compare the coefficients of the balanced equation. However, you have provided the amounts of reactants in terms of volume and moles, without giving the balanced equation of the reaction.

To calculate the mole ratio, we need to know the balanced equation for the reaction involving Pb(NO3) and NaI. Once we have the balanced equation, we can determine the mole ratio by comparing the coefficients of the reactants.

Please provide the balanced equation for the reaction involving Pb(NO3) and NaI, or let me know if there is anything else I can assist you with.
