Explanation:
In water (h2o) the molecule contains three atoms, you have two hydrogen atoms and you have one oxygen atom and in one mole of water you would have 6.02 * 1023 but you have three and not one. Which means you would have "1.8 * 1024" molecules in h2o.
Hope this helps.
Ответ:
225 - 27.25 + 75.50 + 32.19 - 61.95 - 14.21 = 229.28
So B is the answer
