Solution concentration calculators convert between molarity (mol/L), mass concentration (g/L), and percent concentration (% w/v). Used in chemistry, biology, pharmacy, and food science.

公式

Molarity (M) = Moles / Liters | Molality (m) = Moles / kg solvent | PPM = (mg solute / L solution) × 1,000 for dilute aqueous

ステップバイステップガイド

  1. 1Molarity (M) = Moles of solute / Volume of solution (L)
  2. 2Mass conc (g/L) = Molarity × Molar mass
  3. 3% w/v = (mass of solute g / volume mL) × 100
  4. 4Dilution: C₁V₁ = C₂V₂

解いた例

入力
10g NaCl (M=58.44) dissolved in 250mL water
結果
Molarity = (10/58.44)/0.250 = 0.684 mol/L = 0.684 M
