Mole Conversions 2 Steps

Converting can be done from grams to moles to particles and vice versa step by step or in a two step conversion.

It's possible to go from particles to grams and grams to particles using the simple mole conversions
For example:
6.24 grams of NO3  To particles.
First you would need to find the molecular mass by finding the atomic mass of each seperate element and adding them. The molecular mass in this case would be 60u.

Next you would go from grams to moles and then to particles by

6.24 g x 1 mol/60 g x 6.022x10^23/1 mol
=6.3x10^22 particles (don't forget sig figs)
