Puritatea = volum pur/ volum impur * 100
volum pur = puritatea*volum impur/100=280*80/100=224 m cubi acetilena
randamentul = volum practic/volum teoretic * 100
volum practic = randamentul*volum teoretic/100=224*75/100=168 m cubi acetilena
C2H2 + H2O ---> C3H4O
22,4 litri C2H2........44 g C3H4O
168 m cubi C2H2.............x kg C3H4O        x = 330 kg etanal
