Effusion/diffusion = sqrt(MM2/MM1)

PV = nRT

Heat capacity = c=ms

C = wavelength x frequency (c = 3 x 10^8)

vertex = (-b/2a, f(-b/2a))

volume of cylinder - V= pi x r^2 x h

1 lb = 16 oz.
2.2 lb = 1 kg
2.5 cm = in.

these are some that were useful for the Barron's booklet. Please share!

Countdown: 5 days for June-takers.

Know your metric conversions to like nano to pico, milli to femto, etc...

The mole number

 

[sakigt]

Density = m/v

Molarity = mol solute/ v solution

Red Bull + Studying + Confidence = Great success!

I've got got K-Farenheit-Celsius in my head somewhere. I've got Boyles law by itself, Charles law by itself, and Avogadro's law (and number). Also, volume of an ideal gas at STP, correct me if I'm wrong, but 22.4 L? Sorry but I'm still compiling alot over the past few months. Great post though to try to get organized.

Volume of a cylinder? I mean, I know those things, but isn't that a geometry question which there are no more of on the pcat?

Overall, I think you're right; alot of these formulas will be outlawed in the PCAT on Saturday. The big question is where does geometry end and trig begin. I think you could argue that some geometry concepts fall into trig as alot of higher level math overlaps with one another.

haha outlawed? maybe if I had avogardro's # tatooed on my inner thigh...

Hope it's in scientific notation then.😀
