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
masa Cd = 4 mol  x  112.41 g Cd
                                 `````````````````    
                                    1 mol Cd
masa = 449.64 g de cadmio

b. Mm Pb = 207.2  g/mol
masa = 2.8 mol Pb  x  207.2 g Pb
                                   ````````````````
                                      1 mol Pb
masa = 580.16 g de plomo

c. Mm As = 74.92 g/mol
masa = 4.9 mol As  x  74.92 gl As
                                   `````````````````
                                       1 mol As
masa = 367.108 g de arsénico

d. Mm Hg = 200.59 g/mol
masa = 6 mol Hg  x  200.59 g Hg
                                ``````````````````
                                    1 mol Hg
masa = 1203.54 g de mercurio
