What does this template do?
Calculate solution volume in liters, required solute moles, and weighed solute mass in grams from molar mass and target molarity.
Volume in liters divides milliliters by one thousand. Solute moles multiplies target molarity by liters, solute mass multiplies moles by molar mass, and mass concentration multiplies molar mass by molarity.
Assumes anhydrous reagent mass at 100 percent purity and final volume brought to mark in volumetric glassware. Hydrate waters and assay purity require adjusting the effective molar mass.
The working tab keeps editable inputs separate from formulas, with 6 populated sample rows, summary KPIs, an in-cell scale bar, and room for 60 records. The Notes tab explains the method and how to extend the range. All example records are fictional and can be replaced. Download a workbook format to retain formulas, or CSV when you need calculated values only.

Questions about this sheet
How is the result calculated?
Volume in liters divides milliliters by one thousand. Solute moles multiplies target molarity by liters, solute mass multiplies moles by molar mass, and mass concentration multiplies molar mass by molarity.
What assumptions should I check?
Assumes anhydrous reagent mass at 100 percent purity and final volume brought to mark in volumetric glassware. Hydrate waters and assay purity require adjusting the effective molar mass.
Can I add more than 60 records?
Yes. Copy the formula columns into new rows and extend every summary range to include them. Keep inputs and formulas in their original columns.
Are the example records real?
No. All example data is fictional and intended to demonstrate the formulas. Replace it before using the workbook for your own work.
