Oblicz skład procentowy alkinu zawierającego 4 atomów węgla w cząsteczce.
mC4H10=mC4+mH10=4*12u+10*1u=58u
mC4-x
mC4H10-100%
48u-x
58u-100%
x=48u*100%/58u
x=83%
mH10-x
10u-x
x=10u*100%/58u
x=17%
Ogolny wzor alkinów to Cn H2n-2
C4H(2x4-2)
C4H6
4x12 + 6x1 = 54
Zawartośc wegla = 4x12 / 54 x 100% =88,89%
Zawartośc wodoru = 6x1 / 54 x 100% =11,11%
