Calculate The Mass Percent Of A NaCl Solution Prepared By Mixing 210 G NaCl With 1250 ML Of Pure Water class=

Answer :

Answer:

[tex]16.8\text{ \%}[/tex]

Explanation:

Here, we want to get the mass percent of a NaCl with 125.0L of pure water

What we have to do here is to divide the mass of the solute by the volume of the solvent and multiply by 100%

Mathematically, we have this as:

[tex]\text{Mass percent = }\frac{mass\text{ of solute}}{\text{volume of solvent}}\times\text{ 100 \%}[/tex]

[tex]\frac{21}{125}\times\text{ 100 \% = 16.8 \%}[/tex]
