Question

Calculate molecular mass of sugar in 547.2gm

Answer 1

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.
