its chemisty heres the question

20. what is the volume at STP of these gases?

3.20 x 10 exponent -23 mol CO2

or can anyone help me on my homework on aim please?

ohh hmmmm this is so long ago i did this.

22.4 liters

^ that is the volume of 1 mole of gas at STP.

although i'm not sure what you are asking exactly ...what gases? and whats with the number?

one mole of any gas at STP is 22.4 L.

I dont know what 3.2 x 10^-23 is.

is that the number of moles you have to find the volume for?

A.Over 9000?
B.Under 5 billion?
C.Less than infinity?
D.12?
E.All of the above
F.None of the above

That's right, there are six options, not four.

Why is it that some folks quote praise from other members in their sig lines?
Its lame.

what about for this question

21. assuming STP, how many moles are in these volumes?

a.67.2mL SO2
B.0.880 L He
c.1.00 X 10^3 L C2H6

Me and my highly trained team of scientists have figured the answer is A: Over 9000!

PV=nRT.
P=1 atm
n=3.2*10^(-23) mol
R=.082(L*atm)/(mol*k)
T=298 K

V=(nRT)/P
alright?

I'm assumming you're just doing ideal gases if you don't know that, but you could do van der waal's equation too.
