Answer:
42.61 g of NaOH.
Explanation:
We'll begin by writing the balanced equation for the reaction. This is illustrated below:
2Na + 2H₂O —> 2NaOH + H₂
Next, we shall determine the mass of Na that reacted and the mass of NaOH produced from the balanced equation. This is illustrated below:
Molar mass of Na = 23 g/mol
Mass of Na from the balanced equation = 2 × 23 = 46 g
Molar mass of NaOH = 23 + 16 + 1
= 40 g/mol
Mass of NaOH from the balanced equation = 2 × 40 = 80 g
SUMMARY:
From the balanced equation above,
46 g of Na reacted to produce 80 g of NaOH.
Finally, we shall determine the mass of NaOH produced by the reaction of 24.50 g of Na. This can be obtained as follow:
From the balanced equation above,
46 g of Na reacted to produce 80 g of NaOH.
Therefore, 24.50 g of Na will react to produce = (24.50 × 80)/46 = 42.61 g of NaOH.
Thus, 42.61 g of NaOH were obtained from the reaction.
