Question

what is the mass, in grams, of one mole of carbon?
12.0107 g
12.0107 × 10²³ g
5.01 × 10²² g
1.000 g
1.99 × 10⁻²³ g

Explanation:

The molar mass of an element is the mass of one mole of that element. For carbon, its molar mass (from the periodic table) is approximately \(12.0107\space g/mol\). This means the mass of one mole of carbon is \(12.0107\space g\). The other options involve incorrect multiplication by Avogadro's number (which is used for counting particles, not for molar mass directly in this context) or incorrect values.

Answer:

12.0107 g
