P$17\mathrm{.}7$ Table P$15\mathrm{.}5$ lists values for dissolved oxygen concen

tration in water as a function of temperature and chloride

concentration.

$($a$)$ Use quadratic and cubic interpolation to determine the

oxygen concentration for T $=12\backslash$deg C and c $=10$ g$/$L$.$

$($b$)$ Use linear interpolation to determine the oxygen con

centration for T $=12\backslash$deg C and c $=15$ g$/$L$.$

$($c$)$ Repeat $($b$)$ but use quadratic interpolation.
