How Many Atoms Are There In 10grams Of Carbon
convert to moles, then multiply by Avogadro's Number
exactly 34.5 atoms
To determine the number of atoms in 10 grams of carbon, we can use Avogadro's number and the molar mass of carbon.
1. Find the molar mass of carbon: The atomic mass of carbon is approximately 12.01 grams per mole. This means that one mole of carbon atoms weighs 12.01 grams.
2. Convert the mass of carbon to moles: Divide the given mass of carbon (10 grams) by the molar mass of carbon (12.01 grams/mol).
10 grams of carbon / 12.01 grams/mol = 0.832 moles of carbon
3. Use Avogadro's number to find the number of atoms: Avogadro's number states that there are 6.022 × 10^23 atoms per mole.
Number of atoms = Number of moles × Avogadro's number
Number of atoms = 0.832 moles × 6.022 × 10^23 atoms/mol
Number of atoms = 5.0 x 10^23 atoms
Therefore, there are approximately 5.0 x 10^23 atoms in 10 grams of carbon.
