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.
