1. Molarity
2.molality
3.normality
......... PLZ HELP ME

Answer 1

Molarity (M) is defined as the number of molesof solute per liter of solution.
molarity = moles of solute/liters of solution

Molality (m) is defined as the number of molesof solute per kilogram of solvent.
molality = moles of solute/kilograms of solvent

Normality (N) is defined as the number of mole equivalents per liter of solution:
normality = number of mole equivalents/1 L of solution
