Answer:

There are #4.17 × 10^23# atoms of carbon-13.

Explanation:

#0.692 color(red)(cancel(color(black)("mol"))) × (6.022 × 10^23color(white)(l) "atoms")/(1 color(red)(cancel(color(black)("mol")))) = 4.17 × 10^23color(white)(l) "atoms"#

Three problems:

  1. You forgot to include the exponent.
  2. You rounded off incorrectly.
  3. The SI symbol for mole is "mol".
