What net charge would you place on a 112 g piece of sulfur if you put an extra electron on 2 in 1012 of its atoms? (Sulfur has an atomic mass of 32.1 grams per mole.) Give your answer in microcoulombs. Remember that extra electrons result in negative charge!
A 68.0-g piece of aluminum has a net charge of +4.40 HC. Aluminum has an atomic mass of 27.0 g/mol, and its atomic number is 13. (a) Calculate the number of electrons that were removed from the initially neutral aluminum to produce this charge. 2.75e13electrons (b) Determine what fraction of the original number of electrons this removed number represents Nost Ntotal (c) By how much did the original mass of the aluminum decrease after charging? kg Need Help?RWatch

A 12.8-g piece of Styrofoam carries a net charge of -0.684 µC and is suspended in equilibrium above the center of a large, horizontal sheet of plastic that has a uniform charge density on its surface. What is the charge per unit area on the plastic sheet?
A 13.4-g piece of Styrofoam carries a net charge of -0.73 µC and is suspended in equilibrium above the center of a large, horizontal sheet of plastic that has a uniform charge density on its surface. What is the charge per unit area on the plastic sheet? ___ µC/m2
A 10.8-g piece of Styrofoam carries a net charge of -0.664 µC and is suspended in equilibrium above the center of a large, horizontal sheet of plastic that has a uniform charge density on its surface. What is the charge per unit area on the plastic sheet? [ ] µC/m^2
1-A piece of ebonite has a net charge of +7.20µC. How many more protons than electron does this piece of plastic have? 2-If particles A, B, and C, with charges -6.0 µC, 8.7 µC, and -5.4 µC respectively, are forcefully thrown together and then separate what is the net charge on particle B? 3- An proton is placed in a constant electric field of 8.16x104N/C. What is the force on the electron? If the electron is released, what is its...
You charge a piece of aluminum foil (mass = 7.55 g) by touching it to a charged rod. The charged rod gives the aluminum foil a charge of 10
1) You have a piece of solid iron containing 2.60 moles of atoms. Suppose one atom in 1012 were missing one electron. What would be the net charge on the iron?
Let's assume you are given two glass jars. Jar #1 has 32.07 g of sulfur and Jar #2 has 112.4 g of cadmium (Cd). Which beaker contains the greatest number of atoms? Choose the best answer. a. Jar #1 because one sulfur atom weighs less than one cadmium atom so you need more of the sulfur atoms to fill the jar. b. Jar #1 because it contains more moles of sulfur atoms than the number of moles of cadmium atoms...
