1.499moles
Given the following parameters
Mass of Carbon = 18 grams
Molar mass of carbon = 12.011 g/mole
Calculate the moles of carbon
[tex]\begin{gathered} \text{Moles of C=}\frac{Mass}{Molar\text{ mass}} \\ \end{gathered}[/tex]Substitute the given parameters
[tex]\begin{gathered} \text{Moles of C=}\frac{18g}{12.011g\text{/mol}} \\ \text{Moles of C}=1.499\text{moles} \end{gathered}[/tex]Hence the number of moles of carbon is 1.499moles
