How do you convert #1.75 * 10^26# atoms of potassium to moles?
As you know
Number of particles = number of moles x Avogadros constant
The number of atoms in potassium will be equal to the number of particles in it since there is 1 atom of potassium
So, to find the number of moles
We will do,
Number of moles = Number of Particles/Avagadros constant
Number of moles = 290.7
