Answer:
0.66 × 10⁴² mol
Explanation:
Given data:
Moles of water = ?
Number of molecules of water = 3.99× 10⁶⁵ molecules
Solution:
The given problem will solve by using 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.
The number 6.022 × 10²³ is called Avogadro number.
For example,
1 mole = 6.022 × 10²³ molecules of water
3.99× 10⁶⁵ molecules × 1 mol / 6.022 × 10²³ molecules
0.66 × 10⁴² mol
