Question
Manganese is a transition element essential for the growth of bones. What is the mass in grams of 3.22 x 1020Mnatoms, the number found in 1 kg of bone? Conversions between moles and mass23
Solution
Para resolver esta pregunta, debemos seguir varios pasos:
-
Determinar la masa molar del manganeso (Mn): La masa molar del manganeso (Mn) es aproximadamente 54.94 g/mol.
-
Calcular el número de moles de átomos de Mn: Utilizamos el número de Avogadro (6.022 x 10^23 átomos/mol) para convertir el número de átomos a moles.
-
Calcular la masa en gramos: Utilizamos la masa molar del manganeso para convertir los moles a gramos.
Por lo tanto, la masa de 3.22 x 10^20 átomos de Mn es aproximadamente 0.0294 gramos.
