Question

Podrian calcular la masa molecular de los siguientes compuestos:
H₂O
CO₂
HNo₃
H₂SO₄

Answer 1

H2O

H: 2 x 1 = 2 g/mol
O: 1 x 16 = g/mol
````````````````````````````
       Mm = 18 g/mol

CO2

C: 1 x 12 = 12 g/mol
O: 2 x 16 = 32 g/mol
````````````````````````````
         Mm = 44 g/mol

HNO3

H: 1 x 1 = 1 g/mol
N: 1 x 14 = 14 g/mol
O: 3 x 16 = 48 g/mol
````````````````````````````
         Mm = 63 g/mol

H2SO4

H: 2 x 1 = 2 g/mol
S: 1 x 32 = 32 g/mol
O: 4 x 16 = 64 g/mol
``````````````````````````````
           Mm = 98 g/mol
