How many moles of carbon are contained in 6.005 g of carbon?

To determine how many moles of carbon are contained in 6.005 g of carbon, you can use the molar mass of carbon. The molar mass of carbon is approximately 12.01 g/mol. To calculate the number of moles, you can use the formula:

Number of moles = mass (g) / molar mass (g/mol)

Plugging in the values:

Number of moles = 6.005 g / 12.01 g/mol

Calculating the above gives:

Number of moles ≈ 0.5000 mol of C

This calculation shows that in 6.005 grams of carbon, there are about 0.5000 moles of carbon. Thus, the choice stating 0.5000 mol of C is correct, as it accurately reflects the conversion from mass to moles using the standard molar mass.
