Molarity Calculator

Calculate molarity, moles, or volume from the concentration formula C = n/V

C = n / V → 4 mol/L = 2 mol / 0.5 L
浓度 (C)

关于这个计算器

摩尔浓度计算器求解 C = n/V，可计算浓度、摩尔数或体积。输入三个值中的任意两个即可求出第三个。适用于化学、实验室工作和溶液配制——支持 mol/L（摩尔浓度 M）、摩尔和升。

常见示例

  • n = 2 mol, V = 0.5 L → C = 4 M
  • C = 1 M, V = 2 L → n = 2 mol
  • C = 0.5 M, n = 1 mol → V = 2 L
  • n = 0.1 mol, V = 0.25 L → C = 0.4 M
  • C = 2 M, V = 0.75 L → n = 1.5 mol
