Molar mass of ammonium sulfate: 132.14 g/mol
Moles: moles = corrected mass / 132.14
Corrected mass: corrected mass = input mass × (purity / 100)
Molarity: molarity = moles / solution volume in liters
From grams per liter: molarity = corrected grams per liter / 132.14
Required mass: mass = target molarity × final volume × 132.14 ÷ (purity / 100)
Dilution: M1V1 = M2V2
Ammonium sulfate is widely used in chemistry and biology. Labs use it for solution preparation, salting out proteins, fertilizer studies, and routine concentration checks. This calculator helps you estimate molarity with practical inputs. You can work from mass and volume. You can also reverse the process and find the mass required for a target solution.
Molarity expresses moles of solute per liter of solution. It is one of the most common concentration units in chemistry. Accurate molarity supports reproducible experiments. It also reduces preparation errors. When ammonium sulfate concentration is correct, reaction planning becomes easier. Buffer preparation and crystallization work also become more reliable.
This page supports several calculation modes. The first mode converts mass, solution volume, and purity into molarity. The second mode converts grams per liter into molarity. The third mode finds the mass needed for a target molarity and final volume. The fourth mode solves dilution questions with the standard relation between stock concentration and final concentration.
The calculator uses the molar mass of ammonium sulfate, which is 132.14 grams per mole. Moles are found by dividing corrected mass by molar mass. Molarity is then found by dividing moles by solution volume in liters. For dilution, the calculator uses M1V1 equals M2V2. Purity adjustment is included because technical grade materials are not always fully pure.
This tool is useful for teaching labs, research benches, agricultural chemistry examples, and preparation planning. It gives fast numbers and a clear result table. The export options also help with documentation. Use the example data table as a quick reference before entering your own values. Small checks like these can save materials and improve repeatability.
Always enter solution volume in liters for the most direct result. If you measure volume in milliliters, convert it first. Check purity when using non-analytical material. Review whether you need solution volume or solvent volume, because they are not always identical after dissolution. For dilution work, make sure the target molarity is lower than the stock molarity. These small checks improve accuracy and reduce wasted reagents.
Molarity means moles of ammonium sulfate per liter of final solution. It helps you describe concentration clearly and compare one prepared solution with another.
This calculator uses 132.14 g/mol for ammonium sulfate. That value is applied in every concentration and mass conversion shown on the page.
Purity matters when the material is not fully pure. The calculator corrects the usable mass before converting it into moles and molarity.
You should convert milliliters to liters before entering the value. For example, 500 mL should be entered as 0.500 L.
Solution volume is the final total volume after dissolution. Solvent volume is only the liquid added before adjustment. Molarity uses final solution volume.
Yes. The dilution mode uses M1V1 = M2V2. It finds the stock volume needed and shows how much solvent to add.
Dilution lowers concentration. If the target concentration is equal to or above the stock concentration, simple dilution alone cannot produce that result.
No. This page focuses on concentration math. It does not adjust for density, expansion, or temperature-dependent solution behavior.
