Question.A chemist measures the output, E (mV), from a pH electrode for different values of pH.When pH = 6.0, the voltage, E = -60 mV, andwhen pH = 8.5, the voltage, E = 90 mV.i) Find the values of m and c, assuming an equation of the form:E = m × pH + cThanks
o(n^2)
You can find this by using Euler's Formula which states: V + F = E + 2 V stands for the number of Vertices F stands for the number of Faces E stands for the number of Edges Plugging in 5 for both F and V we get: 5+5=E+2 10=E+2 8=E Which means there would be 8 edges.
