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.

Gịnị bụ molar?
Molarity (M) bụ moles nke solute kwa lita nke nrụnye. Nrụnye 58.44 g nke NaCl (1 mole) na lita 1 na-enye 1 M nrụnye.
Olee otú m ga-esi nweta moles site na grams?
Wepụ masị n'ime gram site n'ụdị molar n'ime g/mol. 117 g nke NaCl bụ 117 / 58.44 = 2 moles.
Olee uru m ga-achọ maka molar na vólọ́ọ̀mù?
Moles chọrọ = molarity × volum na lita, mgbe ahụ mass = moles × molar mass. Maka 250 mL nke 0.1 M NaCl nke bụ 0.1 × 0.25 = 0.025 mol, banyere 1.46 g. Hazie "solve for" ka mass ka kalkulatọ ahụ mee ya.
Ònye bụ molarịti n'ime lita mmiri ma ọ bụ n'ime lita nke nrụnye?

Gịnị bụ ọdịiche dị n'etiti molar na molar?
Molarity bụ moles kwa lita nke nrụnye na-akpụgharị n'ụzọ dị mfe na okpomọkụ n'ihi na ọbụna vólọ́ọ̀lụ̀ na-agbanwe. Molarity bụ moles kwa kilogram nke nrụnye na ọ bụ okpomọkụ-enweghị nrụnye. Tul ahụ na-ehazi molarity.
Olee otú m ga-esi wepụ ntinye aka?
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.
