I need to make dilutions. The experiment is for pH and Im having a difficult time understanding. Stock solutions: 0.1 M sucrose; 0.2 M acetic acid; 0.2M sodium acetate; 0.2M anhydrous sodium carbonate; 0.2 M sodium bicarbonate.
A) calculate amount of 0.1M sucrose solution and amount dH2O needed to prepare 100mL of unbuffered 20mM sucrose.
B)Acetic Acid: calculate amount of each stock solution & amount of dH2O needed for 100mL of acetate buffer that contains 20mM sucrose, 40mM acetic acid, and 60mM sodium acetate.
C) calculate amount of each stock solution & amount dH2O needed to prepare 100mL of a bicarbonate buffer that contains 20mM sucrose, 22mM anhydrous sodium bicarbonate, and 28mM sodium bicarbonate.

Seriously... i dont think there is any such thing..sure stuff is melting but i was in canada earlier this year and it has been melt at the same rate for many years. Do you think it could just be because of the ice age..still slowing melting back?
And when its all melted what is it going to matter?

When you look at nicely built men, you see this definition that runs from just above the hips and it kind of works it way into the underwear. When swimmers wear low cut speedos, you can see it. what is that definition or muscle called?

Imagine I am 100 light years away from earth. Suppose I have a telescope powerful enough to observe a baby being born. I now travel at .99999% (the limit of 1-) of the speed of light back to Earth. I keep watching the baby. Suppose babies always die in exactly 100 years. At what point in my travel will I see that baby die?

It should be less than 100 years right? Because when I return home (in 100.000...1 years) the baby should be just a pinch over 200 years old. That implies that I observe the baby's life in fast forward?

If nothing travels faster than the speed of light, how am I intersecting photons of light/waves/whatever at a closing speed of higher than the speed of light? Explain.

A student leaves the university at noon (12:00) bicycling south at a constant rate. At 12:30PM a second student leaves the same point and heads west, bicycling 7mph faster than the first student. At 2:00 they are 30 miles apart. How fast is each one going?

Thanks

I dont know how to word my question but here is my best attempt.

Does the signal strength of FM transmission fade if the number of consumers increase ?

Is the assumption that FM waves are similar to electricity in the sense that it has to be produced enough to be consumed by receivers correct ?

According to Einstein's relativity, light only travels through space, not time, so a watch riding on a light wave would never change time (never increase in time). If this is true, then the time light is emitted (born) would be the same time light is absorbed (no longer in existence) in the reference frame of the light. So if light is emitted and absorbed at the same time, then could it have existed at all (in its own reference frame). Also, wouldn't this mean that light travels all distances instantaneously in its own reference frame? Please set me straight if I am not understanding this concept correctly.

As in, there can be no such thing as a lack of matter in a volume.

So the interplanetary and intergalactic "space" is not devoid of matter entirely, it is just in low enough density to be called a vacuum?

Highlighted by the recent discovery of the 3.3milloin old girl skelington,why is it that apes dont still (on the face of what we know) still evolve into man as we know it?.The 2 species seem to be stuck as they are.

No discoveries of apes in progression to being humans..............
