Total charge of electrons in 1.77 Kg of H20

AI Thread Summary
To calculate the total charge of electrons in 1.77 kg of H2O, first determine the number of moles of H2O using its molar mass, which is approximately 18 g/mol. This results in about 98.33 moles of H2O. Each molecule of H2O contains 10 electrons, leading to a total of approximately 9.83E30 electrons in 1.77 kg of H2O. The total charge can then be calculated using the charge of a single electron, which is approximately -1.6E-19 coulombs, resulting in a total charge of about -1.57E12 coulombs. Understanding these calculations is crucial for solving similar problems in chemistry.

Homework Statement


What is the total charge of all the electrons in 1.77 Kg of H20?


Homework Equations


I really just lost on how to do this problem as I missed school today. Any help would be greatly appreciated


The Attempt at a Solution



the 1st step I took was trying to find the total number of electrons and got 1.943E30 but this is probably wrong.

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...
