Calculating Pressure w/ Nitrogen Molecules: Where to Start?

AI Thread Summary
To calculate the pressure of nitrogen molecules, the ideal gas law is a suitable starting point. The kinetic theory of gases provides equations that relate pressure to molecular speed, which can be useful in this context. Given the number of nitrogen molecules, their rms speed, and the volume they occupy, these equations can be applied to derive the pressure. Understanding the mass of nitrogen molecules is also essential for accurate calculations. Utilizing these principles will help in determining the pressure effectively.

If 61022 nitrogen molecules with an rms speed of 450m=s occupy a volume of 2103 cm3, what
is the pressure? Nitrogen molecules have a mass of 28 amu.


I have been giving this but have no idea where to start. Can somebody point me to a starting point so i can have a go at it.

Ideal gas law i would guess
 
Have you met any of the equations from the kinetic theory of gases?
There are a couple that relate pressure of a gas to molecular speed etc.
 

Thread 'Errors and significant figures'

I multiplied the values first without the error limit. Got 19.38. rounded it off to 2 significant figures since the given data has 2 significant figures. So = 19. For error I used the above formula. It comes out about 1.48. Now my question is. Should I write the answer as 19±1.5 (rounding 1.48 to 2 significant figures) OR should I write it as 19±1. So in short, should the error have same number of significant figures as the mean value or should it have the same number of decimal places as...

Thread 'A cylinder connected to a hanging mass'

Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
