How might you use a radioactive isotope to find out whether the oxygen in CO2 comes from sugar or oxygen gas?

A weighted amount of NaCl is completely dissolved in measured Vol of 4.00 M NH3 solution at ice temp, and CO2 is bubbled in. Assume that NaHCO3 is formed until the limiting reagent is entirely used up. The solubility of NaHCO3 in water at ice temp is 0.75 mol/L. | |

Radioactive isotopes are commonly used because they can be an identifying tracer and their route followed through either the body or a chemical reaction.

A strong acid dissociates almost 100% in aq. soln. and gives more no. of H+ ions. A highly concentrated acidic soln. contains more amt. of pure acid.
