11 lis 2024 · The following equation allows you to find the molarity of a solution: molarity = concentration / molar mass. The concentration denotes the mass concentration of the solution, expressed in units of density (usually g/l or g/ml). Molar mass is the mass of 1 mole of the solute. It is expressed in grams per mole.
Use the Molarity Calculator to calculate the mass, volume or molar concentration required to prepare a solution of compound of known molecular weight.
First, rearrange the molarity equation to solve for the mass of solute m: m = M×MW×V = 1 M × 101.1 g/mol × 2 L = 202.2 g. So, you need to weigh out 202.2 grams of potassium nitrate to make 2 liter of a 1 M solution. This free molarity calculator determines any of the four variables in the molarity equation for solutions, given the other three.
25 lis 2010 · Calculator and formulas for conversion between different units of concentration: Molarity, molality, mole fraction, weight percent of solute and grams of solute per liter of solution - descriptive terms for solubility.
The calculators on this page are independent and can be used in any order. The calculators are numbered because sometimes the results of one calculator are used as inputs to a later one. 1. Mass from volume & concentration. 2. Volume from mass & concentration. 3. Molarity from mass & volume. 4. Dilute a stock solution.
To prepare 1 L of 0.5 M sodium chloride solution, then, as per the formula, use 29.22 g of sodium chloride (0.5 mol/L * 1L * 58.44 g/mol = 29.22 g). The mass molarity calculator tool calculates the mass of compound required to achieve a specific molar concentration and volume.
This online calculator can calculate the molar concentration of a solute in a solution, or mass of a solute in a solution with a specific molar concentration.
