Vinegar is a mixture of two compounds and so has neither an Atomic Mass nor an atomic number as those are characteristics of elements only. Vinegar is a mixture of acetic acid and water. Water is composed of hydrogen and oxygen with the formula H2O. The hydrogen's atomic mass and number are both 1 while oxygen's number is 8 and its mass is 16. This gives water a molecular mass of 18.

Acetic acid is composed of carbon, hydrogen, and oxygen with the formula C2H4O2. Carbon has the atomic number 6 and a mass of 12. This gives acetic acid a molecular mass of 60.
