How much water should be added to 15 gram of salt to obtain 15 percent of salt solution |
|
Answer» Answer: Explanation: The mass by mass percentage of a solution is given by the following relation where mass of solution = mass of solute + mass of solution Here, mass of the solute (i.e. salt) = 15 g and the REQUIRED CONCENTRATION of the solution is 15 %. Let the mass of water be a GRAMS. So, 15 = [15 / (15 + a)] X 100 Solving for a, we get a = (100 - 15)g = 85 g Click to let others KNOW, how helpful is it Read more on Brainly.in - brainly.in/question/690226#readmore |
