How do you get a 10 percent solution from a 95 percent solution?

If you mean: % by MASS ( %m/m), it's quite easy to do (based on the 'Mass Conservation Law).
- Measure 10 gram of the 95%m/m original solution, this contains 95% of 10g = 9.5g Solute
- Then add new solvent up to 95g final solution, so adding (95g - 10g =) 85 gram new solvent, then you'll get:
- 9.5g Solute (in 10 g of original solution) in 95g (final) solution, thus 9.5g S / 95g = 10%m/m
However if the meaning was: % by Volume ( %v/v) then calculation appears to get very complicated, but not impossible if you know at least the density values of all solutions (original 95%v/v and final 10%v/v) and of the solvent.
(In that case mail me: JoppeDeQuint at answers dot com).
DO NOT ever use: (orig. volume) + (added volume) = final volume.
It's only a rule of thump, an approximation. This is because fluids can contract on mixing at dilution. There is no rule such as: conservation of volume.
Your case: 10 ml + 85 ml (is not equal but) < 95 ml final solution.

Out of possible 250 marks Keith scored 91 percent How many extra marks would he have needed to score 95 percent?
Solution if one acts before thinking:91% of 250 = 227.595% of 250 = 237.5(237.5) - (227.5) = 10 extra marks required to raise score to 95%.===============================================Solution if one thinks before acting:Additional score required = (95% - 91%) = (4% of 250) = 10 marks
