    Aluminum Spheres
AI Thread Summary
Each aluminum sphere has a mass of 0.0250 kilograms, which converts to 25 grams. Given that the atomic mass of aluminum is 26.982 grams per mole, each sphere contains approximately 0.9265 moles of aluminum. Since aluminum has an atomic number of 13, each atom has 13 electrons, leading to a calculation of about 7.25 x 10^24 electrons for both spheres combined. The user is seeking clarification on the correct answer, as their previous calculation was marked incorrect. Accurate calculations and understanding of moles and atomic structure are crucial for solving this problem.

Two small aluminum spheres, each of mass 0.0250 kilograms, are separated by 80.0 centimeters.

How many electrons does each sphere contain? (The atomic mass of aluminum is 26.982 grams per mole, and its atomic number is 13.)

The attempt at a solution
I said that there are 6.02*10^23 atoms in a mole, and noted that after converting the mass into grams each sphere has .9265 moles. If the Aluminum spheres are uncharged there are 13 electrons per atom. I multiplied all three together to get 7.25*10^24 total electrons, but this comes up as the wrong answer.

Any guidance as to what I'm doing wrong will be highly appreciated, thanks

Thread 'Struggling to understand the concept of this question (ice cube in water optics question)'

TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...

Thread 'Variable mass system : water sprayed into a moving container'

Starting with the mass considerations #m(t)# is mass of water #M_{c}# mass of container and #M(t)# mass of total system $$M(t) = M_{C} + m(t)$$ $$\Rightarrow \frac{dM(t)}{dt} = \frac{dm(t)}{dt}$$ $$P_i = Mv + u \, dm$$ $$P_f = (M + dm)(v + dv)$$ $$\Delta P = M \, dv + (v - u) \, dm$$ $$F = \frac{dP}{dt} = M \frac{dv}{dt} + (v - u) \frac{dm}{dt}$$ $$F = u \frac{dm}{dt} = \rho A u^2$$ from conservation of momentum , the cannon recoils with the same force which it applies. $$\quad \frac{dm}{dt}...
