Which has more atoms: a 1-g sample of carbon-12 or a 1-g sample of carbon-13? explain?

Carbon-12

Explanation:

Let's consider Avogadro's number: 1 mole of atoms has 6.02 × 10²³ atoms.

The molar mass of the isotope carbon-12 is 12 g/mol. The atoms contained in 1 g of ¹²C are:

The molar mass of the isotope carbon-13 is around 13 g/mol. The atoms contained in 1 g of ¹³C are:

There are more atoms in a 1-g sample of ¹²C than in a 1-g sample of ¹³C.
