ple?
yes, because you know that each mole contains 6.02 x 1023 molecules

yes, as long as you can also measure the mass of the sample

Answer:

The correct option is A

Explanation:

Avogadro's number (6.02 × 10²³) is used to calculate the actual number of ions/atoms/moles present in the molecules of a chemical compound. To do that, avogadro's number is multiplied by the number of molecules of the compound - this is because the number of atoms/ions/moles present in one mole of any substance/compound is 6.02 × 10²³. Hence, one can calculate the the number of moles in the sample because the avogadro's number and the number of molecules of the unknown sample is known.
