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
