Question

Calculate molarity of 16 g of naoh dissolved in 100 ml water

Answer 1

hey mate!

molarity = (given weight/ molecular weight) / volume of solution in litre

m = 16/40*1000/100

m = 4molal

Answer 2

Hey mate !!

Here's the answer !!

Molarity = Number of moles / Amount of solution ( In litres )

NaOH molar mass = 23 + 16 + 1 = 40 g

=> Number of moles in 16g = 16g / 40 g = 0.4 mole

Amount of water = 0.1 litres

Molarity = 0.4 Mole / 0.1Litres

=> Molarity = 4 M

Hope my answer helps !
