A 51.0 mL
aliquot of a 1.60 M
solution is diluted to a total volume of 258 mL.
A 129 mL
portion of that solution is diluted by adding 143 mL
of water. What is the final concentration? Assume the volumes are additive.

Explain how the integumentary system plays a crucial role in the ability to maintain homeoestasis

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.
