Question

calculeaza volumul de metan ce se gaseste in 5 kg de gaz natural, daca partea de masa a metanului in gazul natural este de 98%

Answer 1

1 Kg CH4.................16 Kg
4.9 kg CH4.................xKg
x=4.9*16=78.4 Kg CH4
n=m/M=4.9/16=0.30625 kmoli=306.25 moli CH4
n=V/Vmolar =>V=n*Vmolar(c.n)=306.25*22.4=6860 L CH4
5*98/100=4.9kg CH4
