Calculating the volume needed of a compound
« on: January 16, 2020, 08:30:44 AM »
Hi, everybody!

I want to calculate the volume needed of hydrogen peroxide (H2O2) that I need to add to a solution of sucrose (C12H22O11) (8g of sucrose/ 8 liters of distilled water).

Sucrose and H2O2 has a relation of 1:20 mol.

Additional info:
MM sucrose: 342,3 g/mol
MM H2O2: 34 g/mol
density H2O2: 1.45 g/mL
%(m/m) H2O2: 30%

Thanks in advance! Have a good day :)

There is no relation. What should the Peroxide do. Oxidizing of the sugar?  If yes then you need a balanced redox reaction equation. If not then it doesn't matter you can add how much you like.

Or do you want the mixture 1:20 mole.

Convert 8 g sugar to mole. Then multiply this with 20 and calculate back the mass of peroxide.
This is 100% , calculate to 30% and then calculate volume by using the specific gravity.

The molar ratio of both reagents is defined in a different way (1:20)
