Mass percent of Sodium Chloride solution prepared by mixing is 21.875%.

A mixture is a chemical substance comprised of two or more unrelated chemical components. A mixture is a physical combination of two or more distinct substances that can take the form of solutions, suspensions, or colloids. Solutions of salt and water are an example of a homogeneous mixture, whereas sand and water and oil and water are instances of heterogeneous mixtures.

Density of Water = 1g/mL

So, 125 mL of water weighs 125g

Mass of [tex]NaCl[/tex] = 35.0g

Total mass of solution = 125g+35g = 160g

Mass % of [tex]NaCl[/tex] =(Mass of [tex]NaCl[/tex] / Total Mass ) × 100

= (35/160) × 100

= 21.875%
