Graphpad Molarity Calculator

"I have 5mg of a compound. How much buffer do I add to make a 1µM stock?"

| You want → | You know → | Do this in calculator | |------------|------------|----------------------| | | M, V, MW | Enter M, V, MW → hit Mass | | Molarity | Mass, V, MW | Enter Mass, V, MW → hit Molarity | | Volume | Mass, M, MW | Enter Mass, M, MW → hit Volume | graphpad molarity calculator

You can solve for any of these three, provided you know the other two. "I have 5mg of a compound

| Goal | What to calculate | |------|------------------| | Prepare a standard curve stock | Mass from desired M and V | | Determine concentration of your made-up solution | Molarity from mass and V | | Dilute a known mass into a specific molarity | Volume from mass and M | | Convert between % solution and molarity | Use MW and density – GraphPad’s tool alone doesn’t handle % directly, but you can manually convert % (w/v) to g/mL first. | | I’ve recently started relying on the for

I’ve recently started relying on the for all my solution prep. It simplifies the complex relationship between mass, molecular weight, volume, and concentration into a clean, three-step interface.

Stop doing mental gymnastics in the lab. Save the brainpower for analyzing the data, not mixing the reagents.
