Question

The teacher instructed three students A, b and C respectively to prepare a 50% (mass by volume) solution of NaOH. Student A dissolved %50g of NAOH in 100 mL of water. Student B dissolved 50 g of NAOH in 100g of water. Student C dissolved 50g of NAOH in water to make 100 mL of solution. which one of them has made the desired solution and WHY?

Answer 1

C has made the desired solution.
Bcz %(weight/volume) =weight of solute(in gram) /volume of solution(in 100 ml)
So c has made the right solution.
I hope it will help you.
