Question

could u explain to me had a few friends try to help but I'm still lost...

snow My work (Optional) @ -/14.28 points Give the charge, mass and magnitude of weight for 50 moles of a sodium ion with 3 extra electrons. (Avogadro's number is 6.02x1023 and the fundametal charge is 1.602x10:19 C. Assume the isotope wi ani quai number of protons and neutrons.) My Notes kg o Show My Work (optional) 28 points My Notes A clear vinyl: flexible (clear tubing) is lightly rubbed on a polycarbonate with energy associated with friction of 4 J. Both

Explanation / Answer

3 electron per molecule.

and there are 50 moles = 50 x 6.022 x 10^23 molecules

Q = charge on 3 x 50 x 6.022 x 10^23 electrons

Q = (3 x50 x 6.022 x 10^23)(-1.602 x 10^-19)

Q = 1.45 x 10^7 C .......Ans

masss of 1 mol sodium ion = 22.9898 grams

m = 50 x 22.9898

m = 1149.49 g Or 1.15 kg ........Ans

W = m g = 1.15 x 9.81 = 11.3 N .....Ans
