Answer

$2.6\times10^{21}\ atoms\ C $

Work Step by Step

1. Use the molar mass of carbon and Avogadro's number as conversion factors in order to determine the number of carbon atoms. 2. $52\times 10^{-3} g\ C \times\frac{1\ mol\ C}{12.01\ g\ C}\times\frac{6.022\times10^{23}}{1\ mol\ C}= 2.6\times10^{21}\ atoms\ C $
