Question

The following analytical data pertain to water samples from the North Channel area of Lake Huron:

Assume that the Sr/ Sr ratio of component A (Lake Superior) is 0.7180 and that of component 87 86 B (Lake Huron) is 0.7107. Estimate the concentrations of Sr and Ca of water in Lake Superior and Lake Huron from these data and calculate the volume percent concentration of Lake Superior water in each of the samples.

(Answer: Lake Superior water: Sr = 20.06 :g/L, Ca = 12.80 g/mL; Lake Huron: Sr = 102.8 g/L, Ca = 28.25 :g/mL; abundance of Lake Superior water: 89.2 % (1), 65.3 % (2), 48.9 %(3), 43.8 % (4), 36.6 % (5), and 29.2 % (6)).

(Answer: Lake Superior water: Sr = 20.06 :g/L, Ca = 12.80 ½g/mL; Lake Huron: Sr = 102.8 ½g/L, Ca = 28.25 :g/mL; abundance of Lake Superior water: 89.2 % (1), 65.3 % (2), 48.9 %(3), 43.8 % (4), 36.6 % (5), and 29.2 % (6)).

Explanation / Answer

Lake Superior water: Sr = 20.06 :g/L,

Ca = 12.80
