Molarity is the most common way chemists express concentration: the number of moles of solute dissolved per litre of solution, M = moles / litres, with units of mol/L (also written M). The moles of solute come from its mass divided by its molar mass, moles = mass ÷ molar mass, so the full relationship ties together mass, molar mass, volume and concentration. This calculator solves for any one of molarity, mass of solute, solution volume or molar mass, and accepts the volume in litres or millilitres.
As a worked example, dissolving 58.44 g of table salt (NaCl, molar mass ≈ 58.44 g/mol) in enough water to make 1 litre gives 58.44 / 58.44 = 1 mole in 1 L, a 1 M solution. Dissolve 117 g of NaCl instead and you have 2 moles, which in 1 L is a 2 M solution or, in 500 mL, a 4 M solution. Working backwards, to make 250 mL of 0.1 M NaCl you need 0.1 × 0.25 = 0.025 mol, i.e. 0.025 × 58.44 ≈ 1.46 g.
Molarity is the working currency of the lab bench — preparing standard solutions, diluting stock reagents, running titrations and stoichiometry, and mixing buffers all depend on it. Note that it is defined per litre of final solution, not per litre of solvent, so you dissolve the solute and then top up to the target volume rather than adding it to a pre-measured litre of water.
የሚጠየቁ ጥያቄዎች
ሞላሪቲ ምንድን ነው?
Molarity (M) is moles of solute per litre of solution. Dissolving 58.44 g of NaCl (1 mole) in 1 litre gives a 1 M solution.

Divide the mass in grams by the molar mass in g/mol. 117 g of NaCl is 117 / 58.44 = 2 moles.
How much solute do I need for a target molarity and volume?
Moles needed = molarity × volume in litres, then mass = moles × molar mass. For 250 mL of 0.1 M NaCl that is 0.1 × 0.25 = 0.025 mol, about 1.46 g. Set "solve for" to mass to have the calculator do it.

Use C₁V₁ = C₂V₂: the moles stay constant, so concentration times volume before equals after. To make 1 L of 0.5 M from 2 M stock you need 0.5 × 1 / 2 = 0.25 L of stock topped up to 1 L.
