Garlic smell is easily noticable due to the compound that is responsible for this is Allicin , when we analysed this compaound we found the % composition by mass as H: 6.21 percent; C: 44.4 percent; O: 9.86 percent. S: 39.5 percent. you just need to calculate the empirical formula using this composition percent also find out its molecular formula if molar mass= 486 grams?
