Question

what is meant by concentration? a solution contains 50 gram of common salt in 250 gram of water calculate the concentration of the solution​

Answer 1

Answer:

Mass of solute = 50g

mass of solvent = 350g

mass of solution = 50 + 350 = 400g

mass by mass% = mass of solute / mass of solution

mass by mass = 50/400 * 100

= 100/8

= 12.5%

mass by mass % = 12.5%

Therefore the concentration percentage is 12.5%.
