Answer:

Ans=   6.023 × 10²⁴ molecules F₂

Explanation:

moles can be converted to particles using Avogadro's constant (6.023 × 10²³) which is the number of molecules per mole of a substance. E.g In 1.5 moles of fluorine gas, there are (1.5) . (6.023 × 10²³) molecules of gas. its means in 10 moles of Fluorine gas there are (10).(6.023 x 10^23) molecules present .

Ans= 6.023 × 10²⁴ molecules F₂
