How much sucrose do you need to make 50 ml of a 10% solution? sucrose is a solid with a molecular weight of 342.3. show your calculations, and give complete instructions.

5g sucrose

Explanation:

The solution of 50mL can be assumed to the same density as water (1g/mL), and therefore a mass of 50g. A solution of 10% sucrose has 5g of sucrose:

(50g)(0.10) = 5g

In order to make the solution, 5g of sucrose should be added to about 40mL of water and dissolved completely. The solution may then be poured into a 50mL volumetric flask and diluted to the mark.
