Chapter 3: Q3.6 CYL (page 138)

How many moles of sucrose, C12H22O11, are in a 25-g sample of sucrose?

Short Answer

Expert verified

No. of moles of sucrose is equal to \(0.073{\rm{ mol}}\)

Step by step solution

01

Determine molecular mass 

To calculate no of moles of sucrose, we have to evaluate the molar mass of sucrose first.

342.296

02

Determine no of moles

No of moles = \(25{\rm{ g sucrose }} \times {\rm{ }}\frac{{{\rm{mol of sucrose}}}}{{342.296{\rm{ g sucrose}}}} = 0.073{\rm{ mol of sucrose}}\)

Hence, no of moles of sucrose is equal to\(0.073{\rm{ mol}}\)
