Question

How much amount of potassium chloride in gram will have to be heated to prepare 9.6 gram of oxygen gas potassium 39 calorin 35.5 oxygen 16 ​

Answer 1

Explanation:

Therefore, 24.4 grams of potassium chlorate should be decomposed to obtain 9.6 grams of oxygen.

Hope it's Help you

Answer 2

Answer:

Using unitary method:-

1g of  O2 was produced from decomposition of = 244g96g of KClO3

Hence, 9.6g of O2was produced from decomposition of = 9.6g×244g96g=24.4g of KClO3

-Therefore, 24.4 grams of potassium chlorate should be decomposed to obtain 9.6 grams of oxygen.

Note: -

Always try to write balanced chemical reactions for such questions so as to know the number of moles of each compound involved in the reaction which is very helpful in further calculations of concentration terms.

-Kindly prefer to calculate the terms along with the units for better accuracy in results.
