Question

cual es la compocicion porcentual del acido sulforico ( H SO )
2 4

Answer 1

1. Calcular Mm del 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

2. calcular %

% Hidrógeno

      98 g ----- 100 %

         2 g ----   x

        x = 2.04 % H

% Azufre

      98 g ----- 100 %

       32 g ----   x

        x = 32.65 % S

% Oxígeno

          98 g ----- 100 %

          64 g ----   x

        x = 65.30 % O
