</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%

At the end of a hectic comeback, many worry around him of a decline in diet. "His face has changed, he is marked by the weight of power," says one of his staff. Those who see it more regularly minimize. "He has not changed one iota since his election, says one of his relatives. He is always vigilant on all matters. Nothing escapes him. Hence, perhaps, a little fatigue anyway.
