Homework Answers
- As the concentration of the given electrolyte decreases from 0.1M to 0.0005M the equivalent conductivity also decreases and reaches maximum (as per the data availability ) value 0.0005M concnetration
- limiting equivalent conductivity is the conductivity of the electrolyte at zero concentration or infinite dilution where no more rise in the conductivity of the electrolyte is seen eve on further dilution
- So the limiting equivalent conductivity of LiClO4 as per the given data reads at 0.0005M is 104.13
- it's units are Mho.cm2 .g/equivalent

A client of yours wants to find out the best microbial environment for C. elegans. In previous meetings, the client told you that C. elegans feed on bacteria but may also be killed by certain bacteria. Therefore, it is important to figure out what bacteria are beneficial to C. elegans. In particular, the client was interested in studying the association between the density of Gluconobacter and the density of C. elegans. The client had collected some pilot data for this...
