Question

СРОЧНО!! Вычисли общее число атомов в смеси, состоящей из 4 молекул криптона, 3 молекул озона и 6 молекул водорода.

Answer 1

Ответ:

25

Объяснение:

Криптон - одноатомная молекула

Озон - трехатомная О3

водород - двухатомная Н2

4+3×3+6×2=25

Answer 2

Calculating the Total Number of Atoms in the Mixture

To calculate the total number of atoms in the given mixture, we can use the Avogadro's number and the molecular formula of each substance to find the total number of atoms.

1. Molecular Formulas: - Krypton (Kr): Kr (atomic number 36) - Ozone (O3): O3 (3 oxygen atoms per molecule) - Hydrogen (H2): H2 (2 hydrogen atoms per molecule)

2. Calculating the Total Number of Atoms: - Krypton (Kr): 4 molecules - Ozone (O3): 3 molecules - Hydrogen (H2): 6 molecules

Using the Avogadro's number (6.022 x 10^23 atoms/mol), we can calculate the total number of atoms for each substance and then sum them up to find the total number of atoms in the mixture.

- Krypton (Kr): 4 molecules * 1 mol/6.022x10^23 atoms = 4/6.022x10^23 atoms - Ozone (O3): 3 molecules * 3 mol/6.022x10^23 atoms = 9/6.022x10^23 atoms - Hydrogen (H2): 6 molecules * 2 mol/6.022x10^23 atoms = 12/6.022x10^23 atoms

Total number of atoms = (4/6.022x10^23) + (9/6.022x10^23) + (12/6.022x10^23) atoms

Let's calculate the total number of atoms.
