Respuesta:

d. Ninguno tiene la razón

Explicación:

Para convertir masa a moles, necesitamos la masa molar de cada sustancia.

Fernando (58.85 g Fe)

58.85 g × 1 mol/55.85 g = 1.054 mol

23.05 g × 1 mol/22.99 g = 1.003 mol

Carlos (35.45 g Cl)

La masa molar de Cl es 35.45 g/mol.

35.45 g × 1 mol/35.45 g = 1.000 mol

Paola (27.0 g Al)

La masa molar de Al es 26.98 g/mol.
