There are 36.03 grams in 3.00 moles of carbon.
1st) We need to look for the atomic mass of Carbon (C) in the Periodic Table of Elements:
Carbon atomic mass = 12.01 g/mol
2nd) With the atomic mass of carbon and a mathematical Rule of Three we can calculate the grams of carbon in 3.00 moles:
[tex]\begin{gathered} 1\text{ mol - 12.01 g} \\ 3.00\text{ moles - x=}\frac{3.00\text{ moles}\cdot\text{12.01 g}}{1\text{ mol}} \\ \\ x=36.03\text{ g} \end{gathered}[/tex]So, there are 36.03 grams of carbon in 3.00 moles.
