Question

URGENTEEEE !!!!determine el numero de moles de NH3 en 4.8g....procedimiento porfavor

Answer 1

1. calcular masa molecular de l NH3

N: 1 x 12 = 12 g/mol
H: 3 x 1 = 3 g/mol
```````````````````````````
      Mm = 17 g/mol

2. calcular moles aplicando la fórmula n = masa/Mm

n =  4.8  g
     ``````````
     17 g/mol

n = 0.282 moles de NH3
