Calculating Ideal Gas Volume with the Ideal Gas Law

AI Thread Summary
The discussion revolves around calculating the ideal gas volume using the Ideal Gas Law, specifically for a gas at 27.0 degrees Celsius and 1.00 atmosphere pressure. Participants emphasize the importance of converting Celsius to Kelvin for accurate calculations. The formula V=nRT/p is mentioned, but there is confusion regarding the variable 'n', which represents the number of moles. Clarification is sought on how to determine 'n' based on the number of gas particles in a given volume. The conversation highlights the need for a clear understanding of moles in relation to the ideal gas volume calculation.

Consider an ideal gas at 27.0 degrees Celsius and 1.00 atmosphere pressure. Imagine the molecules to be uniformly spaced, with each molecule at the center of a small cube.

What is the length L of an edge of each small cube if adjacent cubes touch but don't overlap?
______________
I know that the ideal gas law states V=nRT/p and that in this case R=8.2057(10^-5) m^3 (atm/mol*K), p=1atm, T=27+273K. What is n? I can't solve without n!

Simply plug and chug.

You may be forgetting to convert 27 centigrade to an absolute temperature scale such as kelvin.Never mind that; I didn't see the second part of your post.As for n, think about how many atoms you are finding the "cube" for.

am i approaching it the wrong way?
 
No you are approaching it the right way.

Think about n. How many moles is one particle?
 
are you looking for 6.02*10^23 as the answer to your ^ question? sorry don't get it even if that's what you're looking for
 

Thread 'Struggling to understand the concept of this question (ice cube in water optics question)'

TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...

Thread 'Variable mass system : water sprayed into a moving container'

Starting with the mass considerations #m(t)# is mass of water #M_{c}# mass of container and #M(t)# mass of total system $$M(t) = M_{C} + m(t)$$ $$\Rightarrow \frac{dM(t)}{dt} = \frac{dm(t)}{dt}$$ $$P_i = Mv + u \, dm$$ $$P_f = (M + dm)(v + dv)$$ $$\Delta P = M \, dv + (v - u) \, dm$$ $$F = \frac{dP}{dt} = M \frac{dv}{dt} + (v - u) \frac{dm}{dt}$$ $$F = u \frac{dm}{dt} = \rho A u^2$$ from conservation of momentum , the cannon recoils with the same force which it applies. $$\quad \frac{dm}{dt}...
