Answer:
9.96 moles of oxygen
Explanation:
Given data:
Number of molecule of oxygen = 6.00×10²⁴ molecules
Number of moles of oxygen = ?
Solution:
1 mole contain 6.022 ×10²³ molecules
6.00×10²⁴ molecules × 1 moles of oxygen / 6.022 ×10²³ molecules
0.996×10¹ moles of oxygen
9.96 moles of oxygen
The number 6.022 × 10²³ is called Avogadro number.
It is the number of atoms , ions and molecules in one gram atom of element, one gram molecules of compound and one gram ions of a substance.
