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

Answer» SOLUTION :`"300 g of 25% solution contains solute = 75 g,400 g of 40% solution contains solute = 160 g"` `"Total solute "=160+75 = 235g,"Total solution "=300+400=700g` `"Mass % of solute in the final solutieon"=(235)/(700)xx100=33.5%` `"Mass % of solute in the final solutieon"=100-33.55=66.5%`. |
