The atomic mass of carbon (C) is approximately 12.01 atomic mass units (u) as listed on the periodic table.
To determine the mass of 0.5 mol of carbon atoms in grams, you can use the concept of molar mass.
The molar mass of carbon can be calculated as follows:
Molar mass of carbon = Atomic mass of carbon (in grams) / Avogadro's number
Molar mass of carbon = 12.01 g/mol / (6.022 x 10^23 mol^(-1))
Once you have the molar mass of carbon, you can calculate the mass of 0.5 mol:
Mass of 0.5 mol of carbon atoms = (Molar mass of carbon) x (0.5 mol)
So, to find the mass of 0.5 mol of carbon atoms in grams, you would multiply the molar mass of carbon by 0.5 mol.
