Example Use Case

Scenario: You need to prepare a 0.855 M NaCl (salt) solution using 100 g of NaCl in 2 liters of water.

Solution Calculation Steps:

  1. Molarity = (Mass) ÷ (Molar Mass × Volume)
    = 100 g ÷ (58.44 g/mol × 2 L)
    = 0.855 M
  2. Mass Concentration = Mass ÷ Volume
    = 100 g ÷ 2 L
    = 50 g/L
  3. Moles of Solute = Mass ÷ Molar Mass
    = 100 g ÷ 58.44 g/mol
    = 1.711 mol

💡 Conclusion: Using this Molarity Calculator, you can instantly compute the molarity of any chemical solution with step-by-step accuracy.
