How many grams of NaOH are produced with the reaction of 5.00 moles of water? *
2Na + 2H20 (arrow) 2NaOH +H2

50g
100g
200g
400g

200 grams of NaOH are produced with the reaction of 5.00 moles of water

Explanation:

First of all you apply a rule of three to know the amount of moles of NaOH as follows: if 2 moles of water produce 2 moles of NaOH, 5 moles of water how many moles would they produce?

moles of NaOH= 5

Being:

the molar mass of NaOH is: 23 g/mole + 16 g/mole + 1 g/mole= 40 g/mole

Then a rule of three applies as follows: if in 1 mole there are 40 g of NaOH, in 5 moles how much mass is there?

mass= 200 g

200 grams of NaOH are produced with the reaction of 5.00 moles of water
