Given:
[tex]mass_{solute} = 5.30 \: g[/tex]
[tex]mass_{solvent} = 19.7 \: g[/tex]
Required:
[tex]\% \: by \: mass[/tex]
Equation:
[tex]\% \: by \: mass = \frac{mass_{solute}}{mass_{solute} \: + \: mass_{solvent}} \times 100[/tex]
Solution:
[tex]\% \: by \: mass = \frac{5.30 \: g}{5.30 \: g \: + \: 19.7 \: g} \times 100[/tex]
Answer:
[tex]\% \: by \: mass = 21.2\%[/tex]
