Glucose contains resveratrol (C14H12O3) to determine the mass ratio of resveratrol and carbon dioxide of the same quality as carbon dioxide
They are x and y, containing carbon equal, according to the mass of an element = the mass of a compound * the elementMass fractionFor C14H12O3, the carbon mass fraction is C%=12*14/ (12*14+12+16*3) *100%=73.68%For CO2, the mass fraction of carbon is 12/ (12+16*2) =27.27%There is x *73.68%=y*27.27%So there's X: y =57:154
