Answer:
4.55 mol of C₂H₂
Explanation:
Let's verify the reaction:
CaC₂ + 2H₂O → C₂H₂ + Ca(OH)₂
Ratio is 1:1, so 1 mol of calcium carbide will produce 1 mol of acetylene.
4.55 mol of CaC₂ will make the same amount of C₂H₂

Hi there,
I believe that your answer to this will be 234 g NaCL
this is because i made a reaction equation:
The reaction equation:
2Na + Cl₂ → 2NaCl
Molar ratio of Na to NaCl = 2 : 2 = 1
Moles of Na = 92/23
= 4
Moles of NaCl = 4
Mass NaCl = moles x Mr
= 234 grams
Hope this is correct :)
Have a great day
