I did not know what to make of this mornings news. A mixture of emptiness (not knowing what to think) and shock still pains my insides. My childhood crush, who I haven't seen in over 2 years is possibly dying from prostate cancer. It has spread to his stomach.
I would like to ask if it is common among young men (20),
and if genetics plays a major role?
(He's father died of prostate cancer before he was born.)
Does he have any chances of survival?

A division of Carter Enterprises produces "Personal Income Tax" diaries. Each diary sells for $8. The monthly fixed costs incurred by the division are $25,000, and the variable cost of producing each diary is $3.

A. What should be the level of sales in order for the division to realize a 15% profit over the cost of making the diaries?

I get the basics of the Nernst equation, so if anyone knows how to do this exact problem, I'd appreciate it!

Given the half reactions:
Ce^(4+) + e− → Ce^(3+) E° = 1.72 V
Fe^(3+) + e− → Fe^(2+) E° = 0.771 V

What volume of 0.36 M Ce4+ solution must be mixed with 40. mL of 0.42 M Fe2+ solution to produce a solution which produces a platinum electrode potential (relative to SHE) of 1.2455 V.?

This is what I have so far:
I know E(cell) = E(cathode) - E(anode), or E(cell)= 1.72-.771 = 0.949 V
E= E(cell) - [0.0257/n]*ln(Q) [[where .0257 is a constant equal to RT/F at 298 K]]
1.2455= 0.949 - (0.0257/1)*ln(Q)

I can solve for the reaction quotient (Q), but I don't know how I'd solve for volume from that. Any help?
