Answer:
254.35 g of NaCl.
Step-by-step explanation:
We'll begin by writing the balanced equation for the reaction between sodium (Na) and chlorine (Cl₂) to produce sodium chloride (NaCl). This is illustrated below:
2Na + Cl₂ —> 2NaCl
Next, we shall determine the mass of Na that reacted and the mass of NaCl produced from the balanced equation. This can be obtained as follow:
Molar mass of Na = 23 g/mol
Mass of Na from the balanced equation = 2 × 23 = 46 d
Molar mass of NaCl = 23 + 35.5
= 58.5 g/mol
Mass of NaCl from the balanced equation = 2 × 58.5 = 117 g
SUMMARY:
From the balanced equation above,
46 g of Na reacted to produce 117 g of NaCl.
Finally, we shall determine the mass of NaCl produced by the reaction of 100 g of Na. This can be obtained as follow:
From the balanced equation above,
46 g of Na reacted to produce 117 g of NaCl.
Therefore, 100 g of Na will react to produce = (100 × 117)/46 = 254.35 g of NaCl.
Thus, 254.35 g of NaCl were obtained from the reaction.
