puritatea=masa pura/masa impura*100=>masa pura = 320*80/100=256 kg
randamentul = masa practica/masa teoretica * 100 => masa teoretica = 256/80 *100 = 320 kg amestec de gaz sinteza
CO + 2 H2 ---> CH3OH
28 g CO......2*2 g H2........32 g CH3OH
x kg CO.......y kg H2.........320 kg CH3OH
x = 280 kg CO si y = 40 kg H2
280:28 = 10 kmoli
40:2=20 kmoli => nr moli total de gaz = 30 kmoli
Volumul total = nr moli total * volumul in conditii normale (nu se specifica alte conditii)
=>volumul total = 30*22.4 = 672 metri cubi gaz de sinteza
