Solution Steps

Step 1: Calculate Molar Mass of Mn
  • Molar mass of Mn (Manganese) = 54.94 g/mol
Step 2: Convert Moles of Mn to Grams
  • \(2.3 \, \text{mol} \times 54.94 \, \text{g/mol} = 126.36 \, \text{g}\)
Step 3: Calculate Molar Mass of C
  • Molar mass of C (Carbon) = 12.01 g/mol
Step 4: Convert Moles of C to Grams
  • \(0.017 \, \text{mol} \times 12.01 \, \text{g/mol} = 0.20417 \, \text{g}\)
Step 5: Calculate Molar Mass of \( \mathrm{H}_{2} \)
  • Molar mass of \( \mathrm{H}_{2} \) (Hydrogen gas) = 2.02 g/mol
Step 6: Convert Moles of \( \mathrm{H}_{2} \) to Grams
  • \(6.2 \, \text{mol} \times 2.02 \, \text{g/mol} = 12.524 \, \text{g}\)

Final Answer

  1. \( \boxed{126.36 \, \text{g}} \)
  2. \( \boxed{0.20417 \, \text{g}} \)
  3. \( \boxed{12.524 \, \text{g}} \)
  4. \( \boxed{540 \, \text{g}} \)
  5. \( \boxed{336.5 \, \text{g}} \)
  6. \( \boxed{1.12 \, \text{g}} \)
  7. \( \boxed{19.04 \, \text{g}} \)
  8. \( \boxed{0.09 \, \text{g}} \)
  9. \( \boxed{1.62 \, \text{g}} \)
