Question

oblicz masy cząsteczkowe acetylenu (C2H2), heksenu (C6H12) i dekanu (C10H22)

Answer 1

C2H2

m= 12 u *2 + 1u * 2 = 26u

 

C6H12

m= 12u * 6 + 1u * 12 =84u

 

C10H22

12u * 10 + 1u * 22= 142u

 

 

Answer 2

C2H2= 2*12+2*1=24+2=26u

 

C6H12= 6*12+12*1=72+12=84u

 

C10H22= 10*12+22*1=120+22=142u

 

mam nadzieje, ze pomogłam ;)
