Answer:

$2.01x10^(21)atoms\ C$

Step-by-step explanation:

First, find the atomic mass of carbon (12.01
(g)/(mol) ). Then use this value and Avogadro's number (
6.022x10^(23) ) to convert grams to atoms:

$0.04g\ C((1\ mol\ C)/(12.01\ g\ C))((6.022x10^(23) atoms\ C)/(1\ mol\ C))=2.01x10^(21)atoms\ C$
