Question

compocicion porcentual del co2

Answer 1

Composicion porcentual del CO2

1. Calcular Mm

C: 1 x 12 = 12 g/mol

O: 2 x 16 = 32 g/mol

````````````````````````````````````````````

    Mm = 44 g/mol

2. calcular la composición porcentual

% Carbono

      44 g  ------ 100 %

       12 g -------    x

             x = 27.273 % C

% Oxígeno

              44 g  ------ 100 %

                32 g -------    x

             x = 72.727 % O
