Atoms can be converted to moles using Avogadro's number, which is 6.022 x 10^23 mol^-1: 1.51 * 10^15 atoms Si) / (6.022 * 10^23 mol^-1) ≈ 2.51 * 10^-9 mol Si.

To convert atoms of silicon (Si) to moles of silicon (Si), you can use Avogadro's constant, which is approximately (6.022 \times 10^{23}) atoms/mol.

- Divide the number of atoms of Si by Avogadro's constant to get the number of moles of Si:

[ \frac{1.51 \times 10^{15} \text{ atoms Si}}{6.022 \times 10^{23} \text{ atoms/mol}} = \frac{1.51}{6.022} \times 10^{15-23} \text{ mol Si} ]

- Calculate the result:

[ \frac{1.51}{6.022} \times 10^{15-23} \text{ mol Si} \approx 2.51 \times 10^{-9} \text{ mol Si} ]

So, 1.51 * 10^15 atoms of Si is approximately equal to 2.51 * 10^-9 mol of Si.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
