Question

determina la masa molar para cada uno de los siguientes compuestos:
a. C2H2
b. (NH4)2SO4
c. C6H8O6
d. PtCl2(NH3)2
e. C19H28O2
Gracias.

Answer 1

a. C2H2
C: 2  x 12 = 24 g/mol
H:  2 x 1 = 2 g/mol
``````````````````````````````
         Mm = 26 gmol

b. (NH4)2SO4
N: 2 x 14 = 28 g/mol
H: 8 x 1 = 8 g/mol
S: 1 x 32 = 32 g/mol
O: 4 x 16 = 64 g/mol
````````````````````````````
       Mm = 132 g/mol

c. C6H8O6
C: 6 x 12 = 72 g/mol
H: 8 x 1 = 8 g/mol
O: 6 x 16 = 96 g/mol
``````````````````````````````
         Mm = 176 g/mol

d. PtCl2(NH3)2
Pt: 1 x  195 = 195 g/mol
Cl: 2 x 35.4 = 70.8 g/mol
N: 2 x 12 = 28 g/mol
H: 6 x 1 = 6 g/mol
````````````````````````````````````
           Mm = 299.80 g/mol

e. C19H28O2
C: 19 x 12 = 228 g/mol
H: 28 x 1 = 28 g/mol
O: 2 x 16 = 32 g/mol
````````````````````````````
           Mm = 288 g/mol
