Calculate molecular mass of sugar in 547.2gm |
|
Answer» Hello Dear. There is the little mistakes in the QUESTION. We have to find the No. of Molecules, not molecular mass. Here is the answer--- →→→→→→→→→→ First of all, Chemical Formula of Sugar = C₁₂H₂₂O₁₁ Molecular mass of the Sugar = 342 gram/mole. Mass of the Sugar = 547.2 grams. Using the Formula, No. of Molecules = No. of MOLES × AVOGADRO's Number = (547.2/342) × 6.022 × 10²³ = 1.6 × 6.022 × 10²³ = 9.6352 × 10²³ molecules. ∴ No. of molecules in 547.2 grams of Sugar is 9.6352 × 10²³ Molecules. →→→→→→→→→→ Hope it HELPS. |
