Question #fee3e

Answer 1

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".
