Question

In 550 gm of solution 440 gm of solvent is there, then calculate the concentration of the solution? ​

Answer 1

Answer:

Explanation:

mass percent =( mass of solute / mass of solution ) × 100 percent

mass of solute (NaCl) is 110gm and

mass of solution is mass of solute + mass of solvent

mass of solution = 440gm + 110gm = 550gm.

Mass percent = (110/550) × 100

= 20 percentage .

Hence the concentration of mass by mass percent is 20 percent .

hope this helps you :)
