Methyl acrylate (chemical formula: \ rm C {4}H{6}O_ {2} Used for making plastics, coatings, and adhesives. Please calculate: (1) The ratio of the number of carbon, hydrogen, and oxygen atoms in the methyl acrylate molecule is ____ (fill in the simplest integer ratio). (2) The mass fraction of element ____ in methyl acrylate is the highest.
Answer: According to the chemical formula, the ratio of carbon, hydrogen, and oxygen atoms in methyl acrylate molecules is 4:6:2=2:3:1; Fill in: \ rm 2:3:1; In methyl acrylate, the mass ratio of carbon, hydrogen, and oxygen elements is: \ rm (12 \ times 4): \ rm (1 \ times 6): \ rm (16 \ times 2)=24:3:16, indicating that carbon has the highest mass fraction; Fill in: Carbon.
