FAQ
What is molarity?
Molarity (M) = moles of solute ÷ liters of solution. 1 M NaCl means 1 mole (58.44 g) of salt dissolved per liter of final solution.
How do I convert grams to moles?
moles = mass ÷ molar mass. E.g. 10 g of NaCl ÷ 58.44 g/mol = 0.171 mol. Enter the molar mass above to get the mass output directly.
What is the difference between molarity and molality?
Molarity is moles per liter of solution; molality is moles per kilogram of solvent. Molality is temperature-independent, which matters in precise lab work.
