Question
How many moles in 22.81 mL of liquid mercury (Hg)? Answer to 3 decimal places.𝜌(Hg) = 13.534 g.mL-1MW(Hg) = 200.59 g.mol-1
Solution
Para determinar cuántos moles hay en 22.81 mL de mercurio líquido (Hg), debemos seguir estos pasos:
-
Calcular la masa del mercurio: Utilizamos la densidad (𝜌) para encontrar la masa (m). Dado que 𝜌(Hg) = 13.534 g/mL y el volumen es 22.81 mL:
-
Calcular los moles de mercurio: Utilizamos la masa molar (MW) para convertir la masa en moles. Dado que MW(Hg) = 200.59 g/mol:
Por lo tanto, hay 1.538 moles en 22.81 mL de mercurio líquido.
