Question

(N-n)Сколько молекул составят 0,02 моль BaO?

Answer 1

N(BaO) = 0.02 mol
N(BaO) = n*Na = 6.02*10²³*0.02 = 0.1204 * 10²³ молекул

Answer 2

To find the number of molecules in 0.02 moles of BaO, we'll use Avogadro's constant, which is approximately 6.022 x 10^23 molecules/mol. Avogadro's constant represents the number of atoms, ions, or molecules in one mole of a substance.

Number of molecules = Number of moles × Avogadro's constant Number of molecules = 0.02 moles × 6.022 x 10^23 molecules/mol

Now, let's calculate it:

Number of molecules = 0.02 moles × 6.022 x 10^23 molecules/mol Number of molecules = 1.2044 x 10^22 molecules

So, there will be approximately 1.2044 x 10^22 molecules in 0.02 moles of BaO.
