Essential analytical chemistry tool for standardizing commercial concentrated acids, bases, and stock reagents.

Calculation Methodology

Molarity (M) = [ 10 * Density (g/mL) * Weight Percent (%) ] / Molar Mass (g/mol). Solute Concentration (g/L) = 10 * Density * Weight %.

Frequently Asked Questions

M = (10 * 1.84 * 98) / 98.08 = 18.38 M, which is the exact stock concentration found in chemistry reagent bottles.
