Are found along volcanic island arcs
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:
0.2544 moles of water were removed from the sample by the heating process.
Explanation:
Mass of empty evaporating dish = 9.687 g
Mass of evaporating dish and sample of hydrate = 18.407 g
Mass of hydrate = 18.407 g - 9.687 g = 8.72 g
Mass of the evaporating dish and hydrate after heating = 14.007 g
14.007 g = mass of dish + mass of dehydrate
Mass of dehydrate = 14.007 g - 9.867 g = 4.14 g
Mass of water evaporated = hydrated sample - dehydrated sample
= 8.72 g - 4.14 g = 4.58 g
Moles of water evaporated :
0.2544 moles of water were removed from the sample by the heating process.
