Question

сколько атома содержится в 0.1 моль S, в 2 моль О2??

Answer 1

1) n(S)=0,1 моль

No=n*$N_A$=0,1*6,02*$10^{23}$=0,602*$10^{23}$

2) n(O2)=2 моль

No=n*$N_A$=2*6,02*$10^{23}$=12,04*$10^{23}$

Answer 2

Number of Atoms in 0.1 Moles of S

To find the number of atoms in 0.1 moles of S, we can use Avogadro's number, which states that there are 6.022 x 10^23 atoms in one mole of any substance.

Calculation: - Number of atoms in 0.1 moles of S = 0.1 moles * Avogadro's number - Number of atoms in 0.1 moles of S = 0.1 * 6.022 x 10^23 - Number of atoms in 0.1 moles of S = 6.022 x 10^22 atoms

Therefore, there are 6.022 x 10^22 atoms in 0.1 moles of S.

Number of Atoms in 2 Moles of O2

Similarly, to find the number of atoms in 2 moles of O2, we can use Avogadro's number.

Calculation: - Number of atoms in 2 moles of O2 = 2 moles * Avogadro's number - Number of atoms in 2 moles of O2 = 2 * 6.022 x 10^23 - Number of atoms in 2 moles of O2 = 1.2044 x 10^24 atoms

Therefore, there are 1.2044 x 10^24 atoms in 2 moles of O2
