<span>Hi,
</span><span>
</span><span>10 gm of alum is dissolved in 90 gm of water . calculate the mass by mass% of the solution
</span>
Mass by mass % = mass of solute / mass of solution * 100
- Solute - alum ( 10 gms)
- Solvent -90gms( water)
Solution = 90+10=100 gms
- % of solute = 10/100*100=10%
- % Of solvent = 90/100*100=90%
