Answer» e given,Mass of = 44 gTherefore, 44 g of contains 12 g of carbon.Let's CALCULATE how MUCH weight of C present in 0.191 g of Given mass of = 0.1172 gTherefore, 18 g of contains 2 g of HydrogenLet's calculate how much weight of H present in 0.1172 g of H.Total mass of carbon and hydrogen = 0.05209 + 0.01302 = 0.06511 gMass of Oxygen = 0.1 - 0.06511 = 0.03489 gLet's convert mass into moles of each element.Simple ratio of each element will beTherefore, empirical FORMULA of COMPOUND will be |
