Molarity Calculator
An educational calculation using C = m ÷ (Mr × V), with mass in grams, molar mass in g/mol and total solution volume in liters.
Volume means total solution volume, not solvent volume. This tool uses a supplied molar mass; it does not parse chemical formulas or give preparation instructions.
