How many grams of NaOh are produced with the reaction of 5.00 moles of water?

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

the answer to your question is c.
