Molarity - Number of moles - Amount of solution - In liters-NaOH molar mass - 23 - 16 - 1 - 40 g-gt- Number of moles in 4 g - 4 g - 40 g - 0-1 moleAmount of water - 0-5 litersMolarity - 0-1 Mole - 0-5 Litres-gt- Molarity - 0-2 M

Calculate the molarity of solution which is made up of $4 g m N a O H$ in $500 m l$ of water.

Molarity = Number of moles / Amount of solution ( In liters)
NaOH molar mass = 23 + 16 + 1 = 40 g
=> Number of moles in 4 g = 4 g / 40 g = 0.1 mole
Amount of water = 0.5 liters
Molarity = 0.1 Mole / 0.5 Litres
=> Molarity = 0.2 M
