Molarity Calculator Guide

Formula: Molarity (M) = moles / liters

To calculate moles: moles = mass (g) / molecular weight (g/mol)

FAQ - Chemical Conversions

How do I convert mg to ml for chemicals?

Use the formula: ml = mg ÷ (density × 1000). For water at 20°C with density 1.0 g/ml: 1000 mg ÷ (1.0 × 1000) = 1.0 ml. Always check the specific density of your chemical.

How many mg is 1 ml of saline solution?

0.9% saline solution has a density of approximately 1.005 g/ml, so 1 ml weighs about 1005 mg. The solution contains 9 mg of NaCl per ml.

How do I calculate molarity from mg/ml?

Molarity (M) = (mg/ml) / molecular weight (g/mol) × 1000. Example: 58.44 mg/ml NaCl: M = 58.44 / 58.44 × 1000 = 1.0 M.

Why does ethanol have different volume than water for same mass?

Ethanol has a lower density (0.789 g/ml) than water (1.0 g/ml). Therefore, 1000 mg of ethanol occupies 1.27 ml, while 1000 mg of water occupies 1.0 ml. Mass and volume are related through density.
