How many sucrose molecules will be in 250 grams
sasho [114]
<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 × \frac{1 mol}{342.297g} × \frac{6.022 * 10^{23} molecules}{1 mol} = 4.398 molecules

There are <em>4.398 sucrose molecules </em>in 250 grams of sucrose.
