Question

How much water is generated when 516 kg of methanol burns perfectly? metanolia palaa täydellisesti?

Answer 1

Write the balanced equation

2CH₃OH + 3O₂ ==> 2CO₂ + 4H₂O ... balanced equation for combustion of methanol

Find moles of methanol used

516 kg x 1 mol / 0.0320 kg = 16,125 moles

Convert this to water generated

16,125 moles CH₃OH x 4 moles H₂O / 2 mols CH₃OH = 32,250 moles H₂O x 0.018 kg / mol = 581 kg H₂O
