How many carbon atoms are there in 3G of carbon?

Answer 1

To find the number of carbon atoms in 3 grams of carbon, first, we calculate the number of moles of carbon in 3 grams. The molar mass of carbon is approximately 12 grams per mole, so 3 grams of carbon is about 0.25 moles. Since one mole contains approximately (6.022 \times 10^{23}) atoms (Avogadro's number), multiplying 0.25 moles by (6.022 \times 10^{23}) gives approximately (1.51 \times 10^{23}) carbon atoms in 3 grams of carbon.
