Question

Sorbitol, an artificial sweetener, has a formula of c9h14o6. what is the mass of one molecule of sorbitol?

Answer 1

The mass of one molecule of sorbitol, C₉H₁₄O₆ is 3.62×10⁻²² g

Avogadro's hypothesis

6.02×10²³ molecule = 1 mole of sorbitol, C₉H₁₄O₆

But

1 mole of sorbitol, C₉H₁₄O₆ = (12×9) + (1×14) + (6×16) = 218 g

Thus,

6.02×10²³ molecule = 218 g of C₉H₁₄O₆

With the above idea in mind, we can obtain the mass of one molecule. Details below.

How to determine the mass of 1 molecule

The mass of one molecule of C₉H₁₄O₆ can be obtained as illustrated below:

6.02×10²³ molecule = 218 g of C₉H₁₄O₆

Therefore,

1 molecule = 218 / 6.02×10²³

1 molecule = 3.62×10⁻²² g

Thus, the mass of one molecule of C₉H₁₄O₆ is 3.62×10⁻²² g
