Question

sacar los moles de 35gr de AgNO3, 130gr de ZnCl2, 420gr de Ag, 300gr Al2O3

Answer 1

calcular moles = ?

mol (n) = masa / Mm

35gr de AgNO3

Mm AgNO3 = 169,87g/mol

mol = 35 g/ 169.87 g/mol

mol = 0.206

130gr de ZnCl2

Mm ZnCl2 =  136,28 gf/mol

mol = 130 g / 136.28 g/mol

mol = 0.954

420  g de Ag

Mm Ag = 107.86 g/mol

mol = 420 g / 107.86 g/mol

mol = 3.894

300 g  Al2O3

Mm Al2O3 = 101.96  g/mol

mol = 300 g / 101.96 g/mol

mol = 2.942
