    Air Moles
AI Thread Summary
To calculate the number of moles of air from a given mass, one must first determine the molar mass of air. The molar mass can be found by analyzing the composition of air, which primarily consists of nitrogen, oxygen, and trace gases. Each component's molar mass can be obtained from the periodic table. Once the molar mass of air is known, the number of moles can be calculated using the formula n = m / molar mass. Understanding the composition of air is essential for accurate calculations.

BY only given the mass of air in a certain sample, how would one calculate the number of moles of air in the sample?

n = m / mass per mole

however, what's mass per mole? and how would you solve for it? thanks.

Determine the molar mass of air, then use mass/molar mass to figure out the moles of air, then utilize that as you wish.
 
yea, that's exactly what I am trying to figure out. How do you find the molar mass of air?
 
To solve for mass per mole (a.k.a molar mass) you need to know the composition of the air. What is air made out of? How would you find the molar mass of hydrogen, oxygen, or carbon? (hint: it's all in the periodic table).
 

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...
