For every 2 Mol NaOH you would get 1 Mol N2H4
Answer:
mass of oxygen = 80.077 grams
Explanation:
From the periodic table, we can find that:
atomic mass of oxygen = 16 grams
atomic mass of phosphorus = 30.97 grams
The balanced equation is:
4P + 5O₂ ..............> 2P₂O₅
From this balanced equation we can note that:
4 moles of P are required to react with 5 moles of O₂
This means that:
4 * 30.97 = 123.88 grams
are required to react with
5 * (16*2) = 160 grams
Therefore, to know the mass of oxygen required to react with 62 grams of phosphorus, all we have to do is cross multiplication as follows:
123.88 grams of phosphorus ..................> 160 grams of oxygen
62 grams of phosphorus .........................> ?? grams of oxygen
mass of oxygen = (62*160) / (123.88) = 80.077 grams
Hope this helps :)
That answer is what characteristic you have.
