Two molecules of hydrogen react with one molecule of oxygen to produce two
molecules of water. how many molecules of water are produced from 2.0 3 1023
molecules of oxygen? how many moles of water are produced from 22.5 moles
of oxygen?

Answer :

(1) The number of molecules of water produced are,

(2) The number of moles of water produced are, 45 moles

Explanation :

The balanced chemical reaction will be,

For 1 :

From the balanced reaction, we conclude that

As, 1 molecule of oxygen react to produces 2 molecules of water

So, molecule of oxygen react to produces molecules of water

Therefore, the number of molecules of water produced are,

For 2 :

From the balanced reaction, we conclude that

As, 1 mole of oxygen react to produces 2 mole of water

So, 22.5 mole of oxygen react to produces moles of water

Therefore, the number of moles of water produced are, 45 moles

i think   the answer is c hope i'm right
