A water contains the following: C(tot, CO3) = 5 x 103 M, C(tot, PO4) = 1 x
10 3 M, and C(tot, NH3) = 1 x 104 M. The water has a pH of 7.7, and the
alkalinity endpoint is set at pH 4.5. What is the alkalinity, in meq/L, of
this water. Express your answer in meq/L to the nearest hundredth (y.yy
meq/L).
