Example of Using Online Molarity Calculator
Suppose you dissolve 10 grams of NaCl (molar mass = 58.44 g/mol) in 0.5 liters of water.
- Calculate moles: 10 ÷ 58.44 ≈ 0.171 moles
- Volume in liters: 0.5 L
- Molarity = moles ÷ volume = 0.171 ÷ 0.5 ≈ 0.342 M
The calculator provides 0.342 M, allowing you to use this solution in your experiments confidently.
