<h2>Answer:</h2>
We will need to know Avogadro's number and the molar mass of sucrose for this problem to do dimensional analysis.
- Avogadro's number: 6.022 × 10²³ molecules
- Molar mass of sucrose: 342.2965 g/mol
250g × ×
= 4.398 molecules
There are <em>4.398 sucrose molecules </em>in 250 grams of sucrose.
