Answer:
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
