%C = (144/342)*100% = 42,1%
%H = (22/342)*100% = 6,4%
%O = (176/342)*100% = 51,5%
sacharoza ---> C₁₂H₂₂O₁₁
C₁₂ - 144u
H₂₂ - 22u
O₁₁ - 176u
=144u+22u+176u=342u
robimy proporcje:
C₁₂ --- C₁₂H₂₂O₁₁
144u --- 342u
x % --- 100%
x=144u*100%/342u=14400%/342≈42,1%
H₂₂ --- C₁₂H₂₂O₁₁
22u --- 342u
y % --- 100%
y=22u*100%/342u=2200%342≈6,43%
100%-42,1%-6,43%=51,47%
Podsumowanie:
węgla (C₁₂) jest 42,1%
wodoru (H₂₂) jest 6,43%
tlenu (O₁₁) jest 51,47%
Odp: Tlenu jest 51,47%, wodoru 6,43%, a węgla jest 42,1%.
