Average distance between water molecules

AI Thread Summary
The average distance between water molecules at room temperature and pressure can be estimated using the density of water, which is 1 g/cm³, and its molecular weight of 18 g/mol. This information allows for the calculation of the number of moles in a given volume, leading to an understanding of molecular spacing. However, direct answers to homework questions are discouraged to promote independent learning. Instead, participants are encouraged to provide hints and guidance. Understanding these concepts is essential for grasping molecular interactions in water.

Does anyone know what the average distance between water molecules at rtp is, or how I could work this out?

Thanks

Taking into account the density of water = 1 Kg/L = 1 g/cm3 and the molecular weight to be 18 g/mol then the number of moles found in unit volume is:

Welcome to the PF, huda123.

Please take care not to give out answers to homework/coursework questions. It is against the PF Homework Help rules. Please see the "Rules" link at the top of the page.

Please instead provide hints, or clarifying remarks, and be tutorial in your help here. Our goal is to help the original poster (OP) to figure out the problem on their own. After all, that is how they will learn the material the best.
 

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...
