Science & Mathematics - 9 November 2006

Do you know why a person can get shocked with a million Volts and live just because the Current level is low. I learned about this in high shcool, and even got shocked by half a million Volts and was fine, I just can't remember the science behind it. All I really know is that its current that harms you, not Voltage. Let me know the scientific explanation or a website that has the explanation. Thanks.

.1234g of orange kool-aid is dissolved in .1 L of water. The absorbance due to yellow 5 and red 40 are A @ 427 nm = .610 and A @ 503 nm = .159.

What is the concentration of each dye?

What is the mole ratio? (moles Y5 / moles R40)

The closest distance is 56 million kilometers. Could astronauts last that long in flight and have enough room for provisions? Would this ever be possible? How fast would the space capsule have to be traveling? I know we have landed several unmanned spacecraft, but each trip was one way only.

Doing a lab on Beer's Law.
If the stock solution contains .750g of glucose (molar mass 180.156g/mol) dissolved in 100mL deionized water. Thus the stock molarity would be .04163M yes?
Then dilutions are prepared with the stock solution with o-toluidine and deionized water to 100mL.

I'm given several values of volume of stock glucose, i.e. 10.00mL, 20.00mL, 25.00mL, etc.

How do I find the concentration of each solution?
