Answer:9.54*10²²
Explanation:Weight of KNO3 = 16g
Molecular mass of KNO3 =39+14+16*3
=39+14+48 =101
Number of moles = W÷M =16÷101 =0.16 mol
We know that number of moles = number of particles/ Avogadro number
So number of particles= number of moles * Avogadro number
= 0.16*6.022*10²³ = 9.54*10²² number of particles
