I read somewhere on here that the night sky is so dark because starlight has yet to reach us from alot of stars. If this is so, does this mean that eventually the night sky will be bright like it is during the day?

I thought that the van't hoff factor is the moles of particles in solution divided by moles of solute. Because the observed van't hoff factor is less than two for my sodium chloride solution, wouldn't the equation be (2X+Y)/(X+Y)=i ? Where x is the moles of solution that will be dissociated, and y is the moles of solute that will remain clumped. assuming X+Y=1, then 2X+Y=i =>
2X+1-X=i => X=1-i ...and the percent of dissociated sodium chloride would be X/1 multiplied by 100?
Can someone tell me why this is wrong?
