If you have 9.0x10^24 molecules of water, how many moles of water do you have?

14.9 moles of water

Explanation:

Given data:

Number of molecules of water = 9.0×10²⁴ molecules

Number of moles of water = ?

Solution:

Avogadro number:

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.

1 mole = 6.022 × 10²³ molecules of water

9.0×10²⁴ molecules ×1 mol /  6.022 × 10²³ molecules

1.49×10¹ moles

14.9 moles
