Question

How many molecules are in 2.00 mol of water?

Answer 1

There are 1.2044 × 10²⁴ molecules in 2 moles of water.

Explanation:

Given: 2 moles of water.

To convert moles of water into molecules by multiplying the number of moles by Avogadro's number (6.022 × 10²³ molecules).

We have to find the number of molecules as,  

Number of molecules = Moles × Avogadro's number

Plugin the values as,  

Number of molecules = 2 × 6.022 × 10²³ molecules

                                    = 1.2044 × 10²⁴ molecules.

So there are 1.2044 × 10²⁴ molecules in 2 moles of water.
