I’m not sure what chemical reaction you are referencing to, but I attached an image below to help you see what I’m saying.
Answer:
The International Bottled Water Association (IBWA), Alexandria, Va., and Beverage Marketing Corporation (BMC), New York, recently released 2015 bottled water statistics showing that Americans' consumption of bottled water increased by 7.9 percent and bottled water sales were up 8.9 percent from the previous year.

Answer:
200g
Explanation:
Step 1:
The balanced equation for the reaction.
2Na + 2H2O —> 2NaOH + H2
Step 2:
Determination of the number of mole of NaOH produced by the reaction. This is illustrated below:
From the balanced equation above,
2 moles of H2O produced 2 moles of NaOH.
Therefore, 5 moles of H2O will also produce 5 moles of NaOH.
Step 3:
Conversion of 5 moles of NaOH to grams. This is illustrated below:
Number of mole of NaOH = 5 moles
Molar Mass of NaOH = 23 + 1 + 16 = 40g/mol
Mass of NaOH =?
Mass = number of mole x molar Mass
Mass of NaOH = 5 x 40
Mass of NaOH = 200g
