A) a picture shows a container that is sealed at the top by a movable piston. Inside the container is a ideal gas at 1.00atm , 20.0 *C, and 1.00L. (The pic is of a 2L container which has a piston pushed downward to the 1L level. Under the piston, under the 1L mark, is a sample...

calculate the mass of this sample: 1.05 * 10 to the power of 26 atoms of neon, Ne(g) I know that I have to first divide by the avagadros constant, then once get the moles I need to multiply by the molar mass of neon to get the grams, I did that sevral times but I keep on ...

I assume you have a sequence of measurements of mols/grams/amount vs time in seconds. amount at start - amount at 1 sec = amount consumed. This answer is general I know but so is your question with no data.

Neon
I need to find out the cost of the inert gas, Neon and it's Normal Phase to finish off a project. I have searched and searched but can't come up with the info needed. Neon is a rare gas, obtained by liquifing air. Its cost for very pure form is about thirty dollars per ten ...
