Mole Conversion: how many moles are in 1.78 x 10^22 atoms of potassium

Explanation:

This can most easily be done by using a proportional equation.

1 mol = 6.02 * 10^23 atoms

x mol = 1.78 * 10^22 atoms

1/x = 6.02 *10^23 / 1.78 * 10^22        Cross Multiply

1 * 1.78 * 10^22 = 6.02 * 10^23 x

x = 1.78 * 10^22 / 6.02 * 10^23

x = 0.029568 mols

This really ought to be 0.0296 mols
