Edward, these two identities are inherent to the idea of a function operating on a variable (or variables, or on anything else!). A function is a mapping of the first thing onto a second thing -- that is, each element of the first thing becomes a distinct element of the second thing. The inverse...

PRESSURE HELP! (answer)

Symmeatra, In order, the steps you need to follow to solve this problem are: 1) determine the molecular mass of CH3I from its formula 2) determine how many moles of CH3I the stated mass provided represents 3) plug this # moles into the general gas law pV = nRT ; use the appropriate...

Roo, See the equation you need to use, in the answer to your other question. Remember that all gases (ideal gases, anyway, which is how you calculate them unless you have specific data otherwise!) behave EXACTLY the same; the only thing that matters is how many molecules of gas or gases are...
