THIS IS A TEXTBOOK QUESTION HURRRY UP PLEASE You perform the conductivity experiment as described in the lab manual using NaCl solutions of known concentrations. You plot the conductivity of your solutions (μS/m) as a function of the concentration (mol/L). You make a trendline with an equation of y = 1.42 x 105 x + 9.94 x 102. You then test the conductivity of an unknown sample of chicken broth. If the chicken broth conductivity is 7.12 x 103 μS/m.  What is the concentration of NaCl in the broth in mol/L?
