What does Avogadro's law say about a gas atSTP? A; 1 L of any gas contains 22.4 moles at STP B; 1 L of any gas has a pressure of 22.4 atm at STP C; All gases are at 22.4 atm at STP D; 1 mole of any gas has a volume of 22.4 L at STP

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.
