Question

I need help with the rest.

Find to three significant digits the charge and the mass of the following particles. Suggestion: Begin by looking up the mass of a neutral atom on the periodic table of the elements in Appendix C. (a) an ionized hydrogen atom, represented as H charge 44 1.6e-19x Check the number of significant figures. C mass 1.67e-27 kg (b) a singly ionized sodium atom, Na charge mass 49 kg (c) a chloride ion CI charge 49.2 mass 49 (d) a doubly ionized calcium atom, Ca++Ca2 charge mass 0 (e) the center of an ammonia molecule, modeled as an N3 ion charge mass (f) quadruply ionized nitrogen atoms, N4+, found in plasma in a hot star charge 40 mass kg (g) the nucleus of a nitrogen atom charge mass 49 kg (h) the molecular on H20 charge mass 4

Answer 1
