Question

How many atoms are in 14 moles of cadmium?

Answer 1

Ответ:

N = n*N(A) = 14moles * 6*10²³atoms/moles = 8.4*10²⁴atoms

Answer 2

To determine the number of atoms in 14 moles of cadmium, we need to use Avogadro's number, which is approximately 6.022 x 10^23 atoms per mole.

First, we need to calculate the number of atoms in one mole of cadmium. Since one mole is defined as the amount of substance that contains the same number of atoms as there are in exactly 12 grams of carbon-12, the molar mass of cadmium (Cd) is required. The molar mass of cadmium is approximately 112.41 grams per mole.

Next, we can use the molar mass of cadmium to calculate the number of atoms in one mole:

Number of atoms in one mole of cadmium = Avogadro's number = 6.022 x 10^23 atoms/mol

Now, we can calculate the number of atoms in 14 moles of cadmium by multiplying the number of moles by Avogadro's number:

Number of atoms in 14 moles of cadmium = (14 moles) x (6.022 x 10^23 atoms/mol) = 8.431 x 10^24 atoms

Therefore, there are approximately 8.431 x 10^24 atoms in 14 moles of cadmium.
