Question

Calculate the molarity of NaOH solution containing 50g

NaOH in 5 litre solution.​

Answer 1

Answer:molarity = no of moles/ volume of solution

Explanation:

Moles = mass/ molar mass. Molar mass of NaOH =40 g/mol. Mass=50 g moles= 50/40 so. No of moles = 5/4 Volume =5 litre and 1 litre = 1 dm3 so 5 litre= 5 dm3 =Volume. So molarity =5/4/5 = Answer
