Find grams of product using a balanced chemical equation

Click For Summary
SUMMARY

The discussion centers on calculating the grams of potassium chloride (KCl) produced from the decomposition of potassium chlorate (KClO3) using the balanced chemical equation 2KClO3 → 2KCl + 3O2. The correct calculation involves converting 25 grams of KClO3 to moles, then using stoichiometry to find the grams of KCl produced. The final result of 15.2 grams of KCl is accurate, but the calculation should explicitly include the stoichiometric conversion factor of 2 moles of KCl produced per 2 moles of KClO3 decomposed.

Homework Statement


2KClO3 → 2KCl + 3O2

How many grams of potassium chloride are produced if 25 g of potassium chlorate decompose


Homework Equations





The Attempt at a Solution



25g * (1 mole KClO3/122.45 g KClO3) *(74.45g/ 1 mole KCl) =15.2 g KCl

is this right??

Final result is OK, although you are missing a conversion factor, one that is crucial for the stoichiometry - 2 moles KCl produced per each 2 moles of KClO3 decomposed. Luckily to you 2/2 is just 1.
