Hey guys!☺️

Got a question for you!☺️❤️✌️
Calculate the percentage composition in terms of mass of a solution obtained by mixing 300g of 25% and 400g of 40% solution.​

Answer 1

hey mate Answer:

According to question,

300g of 25% solution contains solute = (300 x 25) / 100 = 75g

&

400g of 40% solution contains solute = (400 x 40) / 100 = 160g

Total solute = 75 + 160 = 235g

As given in the question, total solution =300 + 400 = 700g

Percentage of solute in the final solution = (235 x100) / 700 = 33.5%

Percentage of water in the final solution = 100 - 33.5 = 65.5%

hope it helps...
