To change molarity to parts per million (ppm), use this formula:
ppm = (Molarity × Molar mass) / Density × 1,000,000
Where:
– Molarity is the solution’s concentration in moles per litre (mol/L)
– Molar mass is the solute’s molecular weight in grams per mole (g/mol)
– Density is the solution’s mass per unit volume in grams per millilitre (g/mL)
What is 0.1 molar in ppm?
For 0.1 molar to ppm, you need the solute’s molar mass and solution density. Let’s say the molar mass is 100 g/mol and the density is 1 g/mL. Then:
ppm = (0.1 mol/L × 100 g/mol) / (1 g/mL × 1,000,000) = 10,000 ppm
How do you calculate ppm from mol%?
Use this formula to get ppm from mol%:
ppm = (mol% / 100) × 1,000,000
For instance, a 0.5 mol% solution would be:
ppm = (0.5 / 100) × 1,000,000 = 5,000 ppm
