A spherical generator is used to produce a -15.00D surface on glass of refractive index 1.80. The diameter of the cutting tool is 80mm and the radius of the cutting surface is 4mm. What is the angle between the axis of the tool and the axis of the lens?

Find the emf for the cell Cr(s) |Cr3+(aq, 0.37 M) || Pb2+(aq, 0.0095 M) | Pb(s). Answer in units of V I don't know what to do
chemistry
.73 - (.05916/6)*log(2)/(2) for Cr? -.13 - (.05916/6)*log(3)/(3) for Pb?
chemistry
I got .6-(.0592/6)*log((.37)^2/(.0095)^3) which ends up being .558V Is that right?

AP CHEM
the voltage would be 1.66 + -.13 which is 1.53V
AP CHEM
I receive the answer: -442866.15 J or -443 kJ with significant figures
