How many molecules are in 2.00 mol of water?

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.

2h2o2--> 2h2o + o2

this reaction is of the spontaneous decomposition of hydrogen peroxide down into water and oxygen.

add 2 molecules of hydrogen peroxide and 2 molecules of water. since oxygen is naturally diatomic, the total number of atoms of each element is now the same on both sides of the equation so it is balanced.

this may not be entirely correct but let me know.

explanation: no but i do not usually comment
