Question

calcule la composición centecimal de PH3

Answer 1

calcule la composición centecimal de PH3

1. Calcular Mm PH3

P: 1 x 31 = 31 g/mol

H: 3 x 1 = 3 g/mol

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

     Mm = 34 g/mol

2. calcular % de P

        34 g ---- 100 %

         31 g -----     x

         x = 91.17 % P

3. Calcular % Hidrógeno

          34 g ---- 100 %

            3 g -----     x

            x = 8.82 % H
