Calculation of the Mass of Polyethylene
  1. First, calculate the molar mass of CaC2 and HC≡CH:
    - Molar mass of CaC2 = 40.08 g/mol (Ca) + 24.02 g/mol (C) = 64.10 g/mol
    - Molar mass of HC≡CH = 12.01 g/mol (C) + 1.01 g/mol (H) = 26.04 g/mol
  2. Next, determine the number of moles of CaC2 in 20 kg:
    - Number of moles = Mass / Molar mass = 20,000 g / 64.10 g/mol ≈ 312.22 mol
  3. Calculate the number of moles of HC≡CH produced from CaC2:
    - Since one mole of CaC2 produces one mole of HC≡CH, the number of moles of HC≡CH = 312.22 mol
  4. Now, find the molar mass of (CH2-CH2):
    - Molar mass of (CH2-CH2) = 12.01 g/mol (C) + 1.01 g/mol (H) x 4 = 58.08 g/mol
  5. Calculate the mass of polyethylene produced from HC≡CH:
    - Mass of polyethylene = Number of moles x Molar mass = 312.22 mol x 58.08 g/mol ≈ 18,134.18 g ≈ 18.13 kg
  6. Therefore, the mass of polyethylene that can be produced from 20 kg of CaC2 is approximately 18.13 kg.
