The molar mass of carbon (C) is 12 g/mol. The moles of carbon are calculated as follows: \[ \text{moles of C} = \frac{0.6 \, \text{g}}{12 \, \text{g/mol}} = 0.05 \, \text{mol} \] The balanced equation for carbon combustion is: \[ C + O_2 \rightarrow CO_2 \] This indicates a 1:1 molar ratio between carbon and carbon dioxide. Thus, 0.05 moles of carbon yield 0.05 moles of CO2. The number of CO2 molecules is determined by multiplying by Avogadro's number: \[ \text{molecules of CO}_2 = 0.05 \, \text{mol} \times 6.02 \times 10^{23} \, \text{molecules/mol} = 3.01 \times 10^{22} \, \text{molecules} \]
