How many atoms are in 6.00 g of carbon-12?

Answer :

Answer: there are approximately 3.00 x 10^23 atoms in 6.00 g of carbon-12.

Explanation:

To calculate the number of atoms in 6.00 g of carbon-12, we can use the following steps:

Determine the molar mass of carbon-12. The molar mass of carbon-12 is equal to the atomic mass of carbon-12 in grams per mole. The atomic mass of carbon-12 is approximately 12.01 g/mol.

Use the molar mass to convert the mass of carbon-12 given in the problem to moles. We can use the following formula:

moles = mass / molar mass

Substituting the values given in the problem, we get:

moles of carbon-12 = 6.00 g / 12.01 g/mol = 0.499 mol

Use Avogadro's number to convert the number of moles to the number of atoms. Avogadro's number is equal to 6.022 x 10^23 atoms per mole. We can use the following formula:

number of atoms = moles x Avogadro's number

Substituting the values calculated in the previous steps, we get:

number of atoms = 0.499 mol x 6.022 x 10^23 atoms/mol ≈ 3.00 x 10^23 atoms

Therefore, there are approximately 3.00 x 10^23 atoms in 6.00 g of carbon-12.
