Answer:
a. is an excel document. i uploaded as an attachment
b. concentration = 0.327
Explanation:
in the graph i uploaded for answer a, the x variable is conductivity, while the y variable is % salinity.
the calculated regression line was calculated using excel =
y = 0.057655X - 0.00891
for answer part b,
we take x = 5.82
when we put this into the y formular
y = 0.057655(5.82) - 0.00891
y = 0.3355521 - 0.00891
y = 0.3266421
this is ≈ 0.327
in conclusion, using the standard curve, the concentration of unknown salt is 0.327. the % salinity = 0.327
