How to Convert Atoms of Carbon to Moles of Carbon?

Explanation:

Step 1: Identify the given value of atoms of carbon, which is 1.81 x 10^24 atoms.

Step 2: Use the conversion factor to convert atoms to moles.

1 mole of carbon = 6.022 x 10^23 atoms of carbon

Step 3: Set up the conversion calculation.

\[ \frac{1.81 \times 10^{24} \text{ atoms C}}{6.022 \times 10^{23} \text{ atoms C} \times \text{mol}^{-1}} = 3 \: \text{mol} \]

Step 4: Calculate the answer.

By substituting the given values into the formula, we get:

\[ \frac{1.81 \times 10^{24} \times \text{C atoms}}{6.022 \times 10^{23} \times \text{C atoms} \times \text{mol}^{-1}} = 3 \: \text{mol} \]

Therefore, 1.81 x 10^24 atoms of carbon is equivalent to 3 moles of carbon.
