Question
What is the number of moles in 432 g Ba(NO)?Group of answer choices0.237 mol1.65 mol3.66 mol0.605 mol
Solution
Para determinar el número de moles en 432 g de Ba(NO), primero necesitamos conocer la fórmula química completa y la masa molar del compuesto. Sin embargo, parece que la fórmula está incompleta. Asumiremos que la fórmula correcta es Ba(NO₃)₂, que es el nitrato de bario.
-
Determinar la masa molar de Ba(NO₃)₂:
- Masa molar de Ba (Bario) = 137.33 g/mol
- Masa molar de N (Nitrógeno) = 14.01 g/mol
- Masa molar de O (Oxígeno) = 16.00 g/mol
La fórmula Ba(NO₃)₂ tiene:
- 1 átomo de Ba
- 2 átomos de N
- 6 átomos de O (porque hay 2 grupos NO₃)
Entonces, la masa molar de Ba(NO₃)₂ es:
-
Calcular el número de moles: Utilizamos la fórmula: Sustituyendo los valores:
Por lo tanto, la respuesta correcta es 1.65 mol.
