Question

The molar mass of carbon is 12.01 g/mol. If a diamond contains 5.0 x 1021 atoms of carbon, this is equivalent to how many moles and how many grams.

Answer 1

To determine the number of moles and grams of carbon in the diamond, we can use the molecular weight of carbon, which is 12.01 g/mol.

First, we need to convert the number of atoms of carbon to moles:

5.0 x 10^21 atoms of carbon x (1 mole / 6.022 x 10^23 atoms) = 8.33 x 10^22 moles of carbon

Now, we can multiply the number of moles of carbon by the molecular weight of carbon to find the number of grams of carbon:

8.33 x 10^22 moles of carbon x 12.01 g/mol = 100.0 x 10^22 grams of carbon

So, there are approximately 100 trillion trillion (100 x 10^22) grams of carbon in the diamond.
