Question

Calculate the percentage composition in terms of a mass of solution obtained by mixing 100g of 30% solution of NaOH and 150g of 40% solution of NaOH

Please answer it..​

Answer 1

Explanation:

the percentage composition in terms of a mass of solution obtained by mixing 100 gram of 30% solution of Naoh and 150 gram of 40% solution of an Naoh is 30 and 60

Answer 2

Answer:

36%

Explanation:

Total mass of the solution = (100 +150)g = 250g

Total mass of the solute = (0.3 × 100) + (0.4 × 150)

= 30 + 60 = 90g

So the mass percentage of the solution

= 90 ÷ 250 × 100

= 36%
