In chemistry lab student is determining the salinity of seawater using a conductivity meter. The student made standards of NaCl solutions and recorded the following data:
% Salinity Conductivity (ms)
0.10 1.83
0.20 3.62
0.30 5.49
0.40 7.09
0.50 8.76
The conductance of a 10 mL sample of unknown was found to be 5.82 ms.
Required:
a. Prepare a standard curve using the data above.
b. Determine the concentration of the unknown salt solution using the standard curve.

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.
