Para determinar cuántas moles de nitrato de plata (AgNO3) hay en 0.34 gramos de la sustancia, primero necesitamos conocer la masa molar del compuesto. La masa molar del AgNO3 se calcula sumando las masas molares de cada uno de sus componentes: Ag (107.87 g/mol), N (14.01 g/mol) y O (16.00 g/mol). La masa molar del AgNO3 es:<br /><br />107.87 g/mol + 14.01 g/mol + (3 x 16.00 g/mol) = 169.87 g/mol<br /><br />Ahora, podemos calcular el número de moles dividiendo la masa dada (0.34 g) entre la masa molar:<br /><br />moles = masa / masa molar<br />moles = 0.34 g / 169.87 g/mol<br />moles ≈ 0.002 mol<br /><br />Por lo tanto, hay aproximadamente 0.002 moles de AgNO3 en 0.34 gramos de la sustancia.
