Answer:

2584 g

Explanation:

The molecular formula for sucrose is C₁₂H₂₂O₁₁, which means its molar mass is 342.3 g/mol.

First we convert molecules into moles by using Avogadro's number:

  • 4.55x10²⁴ molecules ÷ 6.023x10²³ mol/molecules = 7.55 mol

Now we convert moles of sucrose into grams, using its molar mass:

  • 7.55 mol * 342.3 g/mol = 2584 g
