Computing Mass of gas molecule from specific heat

AI Thread Summary
The mass of a gas molecule can be determined using its specific heat at constant volume (c_v). For argon, with a specific heat of 0.075 cal/g·C, the calculation involves converting the heat capacity from per gram to per mole. This is essential to find both the mass of an argon atom and its molar mass. Understanding the relationship between specific heat and molecular mass is crucial in applying the kinetic theory of gases. The discussion emphasizes the need to compare heat capacities to derive the necessary values.

The mass of a gas molecule can be computed from its specific heat at constant volume c_v (note this is NOT C_v)

Take c_v=0.075\frac{cal}{g*C} for argon and calculate (a) the mass of an argon atom and (b) the molar mass of argon.

I just finshed the chapter on Kinetic Theory of gases, but for some reason I am completely jammed on this one.

Can I get a hint to get me going?

You are given a heat capacity per gram. The usual ideal gas statement of heat capacity is per mole. Compare the two to get grams per mole.
 

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'

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...
