Science Buddies: "Ask an Expert"

How do you figure out the sucrose concentration of something.
For example, 15ml of Sprite, How much sucrose concentration would that have?

This is a forum for help with science projects. But here is a helpful site about concentrations: https://www.thoughtco.com/calculating-c ... ion-608178

Hi Daksh,

Concentration is usually calculated by molarity (mol) divided by volume (L). You can calculate the molarity by: mass (g) divided by molar mass (g/mol).

For example, if you want to find the concentration of 1g sucrose in 15 mL of Sprite, you can do this:
- Convert: 15 mL = 0.015 L
- Look up the molar mass of sucrose: 342.2965 g/mol
- Molarity of sucrose = mass (g) divided by molar mass (g/mol):
1g / 342.2965 g/mol = 0.003 mol
- Concentration of sucrose = molarity (mol) divided by volume (L):
0.003 mol / 0.015 L = 0.2 M

Any question, please let me know!

Best,
Elise
