Question

Дано: FeCl3-колличество вещества 0,2моль,-найти N-число атомов на моль

Answer 1

N(FeCl3)=0.2 (моль)
N=n*Na, где Na-число Авагадро = 6,02*10^23 (г/моль)
Т=0,2 * 6,02*10^23= 1,2*10^23 (молекул)

Answer 2

Calculation of N - Number of Atoms per Mole

To find the number of atoms per mole (N) for FeCl3 with a given amount of substance of 0.2 moles, we can use Avogadro's number, which is approximately 6.022 x 10^23 atoms per mole.

The formula to calculate the number of atoms per mole is:

N = n x N_A

Where: - N is the number of atoms per mole - n is the amount of substance in moles - N_A is Avogadro's number

Given that the amount of substance (n) is 0.2 moles, we can substitute these values into the formula:

N = 0.2 x 6.022 x 10^23

Calculating this expression, we find that the number of atoms per mole (N) for FeCl3 is approximately 1.2044 x 10^23 atoms per mole.

Therefore, the number of atoms per mole (N) for FeCl3 with a given amount of substance of 0.2 moles is approximately 1.2044 x 10^23 atoms per mole.
