Molarity (M) is the concentration of a solution, defined as the number of moles of solute dissolved per litre of solution. It is the most commonly used unit of concentration in chemistry.
단계별 가이드
- 1Count moles of solute (mass / molar mass)
- 2Measure volume of solution in litres
- 3Molarity M = moles / litres
- 4To prepare a solution: weigh moles × molar mass of solute, dissolve, transfer to volumetric flask, add solvent to the mark
풀어진 예시
입력
5.85g NaCl (M=58.5) in 500ml water

입력
0.5 mol/L × 2L
결과
1.0 mol solute needed
n = M × V
