SUMMARY

The discussion focuses on preparing a stock solution of resveratrol at a concentration of 1g/L with a final volume of 100mL. To achieve this, 0.1 grams of resveratrol is required, calculated using the molecular weight of 228.24g/mol. The participants confirm that the amount of resveratrol is sufficient for the preparation of the solution. The calculation method involves determining the number of moles based on the mass and molecular weight of the compound.

Homework Statement


I need to make a stock solution of 1g/L. The compound is called resveratrol with a molecular weight of 228.24g/mol. I need the final volume to be 100mL. How do I find the volume of this compound needed to make 1g/L?. I know that the amount of moles is equal to the amount of compound there is divided by the molecular weight. And I'm sure I have enough resveratrol to make 1g/L.

Or would I just say that 0.1grams of resveratrol needs to be added to 100mL?

Yes, that's perfectly enough.
 
Thank you for the quick reply. I highly appreciate it.
