8.0 % w/v
It means 100 mL solution contains 8.0 g KOH
8.0 g KOH required = 100 mL
23 g KOH required = 100×23/8.0 = 290 mL
2)mole =23/56
=0.411 mol
Volume =0.411/0.24
= 1700 mL

To write the percent concentration as a conversion factor and to use the percent concentration as a conversion factor. The percent concentration of a solution can be written in several different ways, including the mass percent, the volume percent, and the mass/volume percent. The percent concentration of a solution can be used as a conversion factor to determine information such as the amount of solute or amount of solution. For example, a 4% (m/m) solution means that there are 4...
