Question

The number of Potassium atoms present in 202g of KNO3 is

Answer 1

Answer ::A KNO3 molecule has 1 Potassium, 1 Nitrogen and 3 oxygen atoms i.e. a total of 5 atoms.

Explanation:

Then in the 202g of KNO3 is So the total is 5 atoms, therefore the atomicity of potassium nitrate is 5. Atomicity is the number of atoms that are present in one molecule of any compound. Here in case of potassium nitrate (KNO3) , there are 1 atom of potassium , 1 atom of nitrogen and 3 atoms of oxygen.
