Question

1.Averigua la masa de un mol de:a.4 moles de cadmio, Cd.b.2.8 moles de plomo, Pb.c.4.9 moles de arsénico, As. d.6 moles de mercurio, Hg.

Answer 1

a.  Mm Cd = 112.41 g/mol

g Cd = 4 moles  x  112.41 g
                              ````````````
                              1 mol Cd

g Cd = 449.64

b)  MmPlomo = 207,20 g/mol

g Pb = 2.8  moles  x  207.2 g
                                 ````````````
                                 1 mol Pb
g Pb = 580.16

c)  Mm arsénico = 74,92 g/mol

g As = 4.9  moles  x  74.92 g
                                 ````````````
                                 1 mol As
g As = 367.108

d)  Mm Mercurio = 200.59 g/mol

g Hg =   6 moles  x   200.59 g
                                 ````````````
                                 1 mol Hg
g Hg = 1203.54
