How to Calculate Kg to Litres for Sodium Hydroxide (50% Solution)
To calculate the volume in litres from a known mass of Sodium Hydroxide (50% Solution), divide the mass in kilograms by the substance density:
Volume (L) = Mass (kg) ÷ 1.525 kg/L
1 Litre Mass1 L = 1.525 kg1525 grams per litre
1 Kilogram Volume1 kg = 0.656 L656 mL per kilogram
