Question

Определите число атомов в 4 молях кислорода​

Answer 1

Ответ:

4,8176×10^24

Объяснение:

В 1 моль 6,022*10^23 молекул, при этом молекула кислорода двуатомна.

N(O)=4*2*6.022*10^23=4,8176×10^24 (4,8*10^24)

Answer 2

Calculating the Number of Oxygen Atoms in 4 Moles of Oxygen

To determine the number of atoms in 4 moles of oxygen, we can use Avogadro's number, which is the number of atoms or molecules in one mole of a substance. Avogadro's number is approximately 6.022 x 10^23.

Avogadro's number: 6.022 x 10^23

Now, we can calculate the number of oxygen atoms in 4 moles using the following formula:

Number of atoms = Avogadro's number x Number of moles

Substituting the values: Number of atoms = 6.022 x 10^23 x 4

Number of atoms in 4 moles of oxygen: 6.022 x 10^23 x 4 = 2.4088 x 10^24 atoms

Therefore, there are approximately 2.4088 x 10^24 oxygen atoms in 4 moles of oxygen.
