Asolution of nacl(aq)nacl(aq) is added slowly to a solution of lead nitrate, pb(no3)2(aq)pb(no3)2(aq) , until no further precipitation occurs. the precipitate is collected by filtration, dried, and weighed. a total of 18.72 g pbcl2(s)18.72 g pbcl2(s) is obtained from 200.0 ml200.0 ml of the original solution. calculate the molarity of the pb(no3)2(aq)pb(no3)2(aq) solution.

The boiling point of propanoic acid is higher than that of 1-butanol because: propanoic acid has a higher molecular weight than 1-butanol. propanoic acid is more soluble in water than 1-butanol. propanoic acid is a better hydrogen bond donor than 1-butanol. propanoic acid forms hydrogen bonded dimers and 1-butanol does not. 1-butanol forms hydrogen bonded dimers and propanoic acid does not.
