WebbThe percentage (by mass) concentration of a solution obtained by mixing 300 g of a 25 % (solution I) and 400 g of a 40 % (solution I I) by mass is (as the nearest integer): Q. 1st Solution-300g of 25% w/w. 2nd Solution-400g of 40% w/w. When both mixed, find the percentage of solute of final solution. WebbWe can consider percent by mass (or weight percent, as it is sometimes called) in two ways: The parts of solute per 100 parts of solution. The fraction of a solute in a solution multiplied by 100. We need two pieces of information to calculate the percent by mass of a solute in a solution: The mass of the solute in the solution.
