How many moles of HCl can form from 25.2 mol of Na2S2O3?

Final answer:

To determine the number of moles of HCl that can form, we need to use the balanced chemical equation and stoichiometry.

Explanation:

To determine the number of moles of HCl that can form from 25.2 moles of Na2S2O3, we need to use the balanced chemical equation between Na2S2O3 and HCl. The equation is:

Na2S2O3 + 2HCl → 2NaCl + H2O + SO2

From the equation, we can see that 2 moles of HCl react with 1 mole of Na2S2O3. Therefore, if we have 25.2 moles of Na2S2O3, we can form 2 times that amount of HCl, which is 50.4 moles (option C).

How many moles of HCl can form from 25.2 mol of Na2S2O3? The number of moles of HCl formed is 50.4 mol of HCl.
