Question

1. Find the total charge of the protons present in 6.5 moles of Beryllium, an element with 4
electrons per atom. Avogadro's number = 6.022 x1025 e = 1.6 x 10-90
2. How many moles of Helium do you have if the charge of the protons present is 5.456 x 10-7C?
3. At what distance is the force between an 11.2 x10°C charge and a -29.1 x10 C charge equal
to 1.77 N?
F = k al k=9x10°
