Question

calculate the number of Gram molecules of sugar in 547.2 gram

Answer 1

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.

Answer 2

Answer:

Explanation:

no of gram molecules=547.2/342*(6.023*10^23)
