# How do you convert 1.75 * 10^26 atoms of potassium to moles?

Feb 18, 2016

Simple
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
= $1.75 \times {10}^{26} / 6.02 \times {10}^{23}$
= $290.7$
Number of moles = 290.7
