A solution is obtained by mixing 300 g o | Class 12 Chemistry Chapter Solutions, Solutions NCERT Solutions

Question:

A solution is obtained by mixing 300 g of 25% solution and 400 g of 40% solution by mass. Calculate the mass percentage of the resulting solution.

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 = 33.57%

Percentage of water in the final solution = 100 - 33.5 = 65.43%
