1. if 500 ml of a 3 l sample of 0.20 m sodium chloride solution is spilled, what is the concentration of the remaining solution? a. 300 m b. 033 m c. 15.2 m d. 20 m

D. 0.2 M

The concentration of a solution is basically the ratio of the solute present to the solvent in the solution. This is an intrinsic property, independent of the amount of solution that is present. A similar example is that of density. No matter the size of a sample, the density and concentration of that sample remain constant.

Its a hope this
