How many atoms are there in 144g of sucrose, C12H22O11 or sugar molecules?

2.53×10²³ atoms

Explanation:

To solve this, convert grams to moles and moles to atoms.

To convert grams to moles, use the molar mass of C₁₂H₂₂O₁₁ (342.296 g/mol).  Divide the mass by the molar mass to get moles.  Moles = 0.4207

To convert moles to atoms, use Avogadro's number (6.022×10²³ atoms/mol).  Multiply moles by Avogadro's number to get atoms.  Atoms = 2.53×10²³
