Answer 1

Решение:
1)n->N
N(O2)=n*Na
N(O2)=6*10^23*2=12*10^23
Ответ:N(O2)=12*10^23

Answer 2

Calculating the Number of Oxygen Molecules in 2 Moles of O2

To determine the number of molecules of oxygen in 2 moles of O2, we can use Avogadro's number, which states that one mole of any substance contains 6.022 x 10^23 molecules.

Avogadro's number: 1 mole = 6.022 x 10^23 molecules

Now, let's calculate the number of molecules of oxygen in 2 moles of O2.

Using Avogadro's number: - 1 mole of O2 contains 6.022 x 10^23 molecules - Therefore, 2 moles of O2 contain 2 * 6.022 x 10^23 molecules

So, 2 moles of O2 contain 1.2044 x 10^24 molecules of oxygen.
