W(C)=85.71%=0.8571
W(H)=14.29% = 0.1429
D(Н2)=42
CxHy-?
M(H2) = 2 g/mol
M(CxHy)=D(H2)*M(H2)=42*2g/mol=84 g/mol
m(CxHy) = n(CxHy) * M(CxHy) = 1 mol*84 g/mol = 84 g
m(C) = m(CxHy) * W(C) / 100% = 84 * 85.71% / 100% = 72 g
m(H) = m(CxHy) * W(H) / 100% = 84 * 14.29% / 100% = 12 g
n(C) = m(C) / M(C) , M(C) = 12 g/mol
n(C) = 72 / 12 = 6 mol
n(H) = m(H) / M(H) , M(H) = 1 g/mol
n(H) = 12 / 1 = 12 mol
n(C) : n(H) = 6 :12
