reactia va fi:
[tex] CH_{2}= CH_{2} + H_{2}O = CH_{3}-CH_{2}-OH [/tex]
se folosesc relatiile:
d=ms/Vs, unde d-densitatea
ms-masa de solutie
Vs-volumul de solutie
c=md*100/ms, unde c-concentratia
md-masa dizolvata
ms-masa de solutie
0.25 L alcool= 250 mL alcool
ms=d*Vs=0.8*250=2000g solutie alcool
c=md*100/Vs, de unde scoatem md
md=c*ms/100=92*2000/100=1840 g alcool (care se foloseste pe reactie)
22.4 L M=46 g
[tex] CH_{2}= CH_{2} + H_{2}O = CH_{3}-CH_{2}-OH [/tex]
V 1840 g
V=22.4*1840/46=.... L etena
