how many molecules of water are produced from 2.0 x 10^23 molecules of oxygen?
how many moles of water are produced from 22.5 moles of oxygen?
2.0 x 10^23 molecules of oxygen (O2) contain 4.0*10^23 atoms of O, and will make that many (4.0*10^23) molecules of H2O.
Similarly, 22.5 moles of O2 aill make 45 moles of H2O, assuming a sufficient amount of H2 is also provided.
To determine the number of water molecules produced, we need to understand the chemical equation for the reaction. In this case, when one molecule of oxygen reacts, it produces two molecules of water. The balanced equation is:
2H2 + O2 -> 2H2O
Therefore, two molecules of water are produced for every one molecule of oxygen reacted.
For the first question:
If we have 2.0 x 10^23 molecules of oxygen, we can multiply this number by 2 to find how many water molecules are produced.
2.0 x 10^23 * 2 = 4.0 x 10^23 water molecules are produced.
For the second question:
If we have 22.5 moles of oxygen, we can use the mole ratio to determine the number of moles of water produced.
According to the balanced equation, 1 mole of oxygen produces 2 moles of water.
So, we can multiply the given number of moles of oxygen by the mole ratio to find the moles of water.
22.5 moles of oxygen * 2 moles of water / 1 mole of oxygen = 45 moles of water are produced.
Please note that in the second question, we assumed that the reaction goes to completion, meaning all the oxygen is completely converted to water.
