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.

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 don't know if I am doing the ideal gas law or grahams law...

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...

for my last 2 questions, I cannot figure out how to set it up. what numbers do I use?

How is this problem done? IF f(x)=2x^2-8x-3 FIND f(-2)

How is this problem done? IF f(x)=2x^2-8x-3 FIND f(-2) algebra 2 - bobpursley, Saturday, January 16, 2010 at 1:42pm Put in for x the value -2, and compute f(-2) algebra 2 - hellogoodbie, Saturday, January 16, 2010 at 1:47pm so is the answer f=21/2? if tha...

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?

length=2w-3

hey! i've been waiting for my question to be answered. if of you have another question, please post a new question.

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

Oh! I think I understand now

so what would be rate 1 and 2?

so is the answer f=21/2? if that is right, thank you bobpursley

where did u get the 4 from?

Wow, I'm so confused. Can somebody just solve this problem step by step please?
