I am now stumped on another problem. How many times greater is the rate of diffusion of helium gas,HE, than that of carbon dioxide gas CO{tiny 2 at bottom}, at the same temperature and pressure? please tell me how to set this problem up and tips on how to do it.
*January 11, 2010*

so what would be rate 1 and 2?

I'm stumped again :( the question is - A gas sprayed from an aerosol can effuses 5.06 times slower than oxygen.If the molar mass of oxygen is 32.g/mol, what is the molar mass of the unknown gas? I dont know if I am doing the ideal gas law or grahams law or how to set it up...

Oh! I think I understand now

So is grams, n in the formula PV=nRT? I think I am starting to understand this.

So here I am doing my HW worksheet on the ideal gas law/graham's law ad I have gotten to this one problem where I am totally stuck and confused. Please help me by telling me how to set this up and giving me tips, if necessary. What is the mass (in grams) of ammonia gas (NH...

**chemestry**

so all i do is add 273.15 to the temperature in celsius( sorry about the typo. i no i spelled chemistry wrong too)and then multiply/divide everything?
*January 11, 2010*

**chemestry**

how do you solve the ideal gas law when you are given the temperature in celcius instead of kelvin. Heres an example question. Calculate the volume occupied by 3.25 moles of carbon dioxide at 25degrees celcius and 750mm Hg.
