Question

calculate the concentration in term of mass by mass percentage of solution of 45g of KCL present in 500g of solution​

Answer 1

To calculate the mass percent or weight percent of a solution, you must divide the mass of the solute by the mass of the solution (both the solute and the solvent together) and then multiply by 100 to change it into percent.

Answer 2

Answer:Calculate the concentration in term of mass by mass percentage of solution of 45g of KCL present in 500g of solution

We know,

Mass of solution = Mass of solute +

Mass of solvent

45+500g=545g

Mass percentage of solution

Mass of solute/ Mass of solution = ×100

45/500 × 100 = 9%
