Answer:
112 mL
Explanation:
The formula for percent by volume is
If you have 250 mL of a solution that is 44.8 % v/v,
The van't Hoff factor is the ratio between the amount of particles produced when a substance is dissolved and the amount of substance being dissolved. If ionization is 0 percent then it would mean that the substance do not dissociate into particles so the van't Hoff factor would be 1. However, when the percent ionization is 100%, then it fully dissociates into ions. For H2SO4 at 100% ionization, the vant hoff factor should be three, two hydrogen ions and one sulfate ion.
Answer:
During separation of substances with different boiling points, fractional distillation is used.
During separation of substances in an eutectic mixture or azeotropic mixture, steam distillation is used.
