Sol:- Mass of solute = 15g
Mass of solvent =15g
Mass of solution = Mass of solute + Mass
of solvent.
= 15g + 15g
= 30g
Mass of mass% =
![\frac{mass \: of \: solute}{mass \: of \: solution} \times 100 \frac{mass \: of \: solute}{mass \: of \: solution} \times 100](https://tex.z-dn.net/?f=+%5Cfrac%7Bmass+%5C%3A+of+%5C%3A+solute%7D%7Bmass+%5C%3A+of+%5C%3A+solution%7D++%5Ctimes+100)
![= \frac{15}{30} \times 100 \\ = 50\% = \frac{15}{30} \times 100 \\ = 50\%](https://tex.z-dn.net/?f=+%3D++%5Cfrac%7B15%7D%7B30%7D++%5Ctimes+100+%5C%5C++%3D+50%5C%25)
Mass of solvent =15g
Mass of solution = Mass of solute + Mass
of solvent.
= 15g + 15g
= 30g
Mass of mass% =
