Answer:
5.5 moles of sodium are produced
Explanation:
Given data:
Number of moles of hydrogen = 2.75 mol
Number of moles of Na produced = ?
Solution:
Chemical equation:
H₂ + 2NaCl → 2HCl + 2Na
Now we will compare the moles of hydrogen and sodium from balance chemical equation:
H₂ : Na
1 : 2
2.75 : 2/1×2.75 = 5.5 mol
Thus, 5.5 moles of sodium are produced.
