Question

Calculate the number of C atoms in 0.522 mol of C.

Express the number of atoms of carbon numerically.
Nc = ________ atoms of C

Answer 1

The number of C atoms in 0.522 mol of C is:

Nc = 0.522 mol * Avogadro's number

Nc = 0.522 mol * 6.022 x 10^23 atoms/mol

Nc = 3.145 x 10^23 atoms

So there are 3.145 x 10^23 atoms of C in 0.522 mol of C.
