Determine el número de moles presentes en una esfera de titaniode 0.5 cm de radio, sabiendo que la densidad del titanio es de 45
ludmilkaskok [199]

Answer:

0.0493 moles de Titanio

Explanation:

Primero, debemos hallar el volumen de la esfera. Usando la densidad podemos hallar la masa de titanio y usando la masa atómica encontraremos las moles de titanio:

<em>Volumen de la esfera:</em>

<em>Volumen esfera  = 4/3π * Radio³</em>

Volumen = 0.5236cm³

En m³ (1m³ = 1x10⁶cm³):

0.5236cm³ * (1m³ / 1x10⁶cm³) = 5.36x10⁻⁷m³

<em>Masa en gramos:</em>

5.36x10⁻⁷m³ * (4507kg / m³) = 2.36x10⁻³kg * (1000g / 1kg) = 2.36g de Titanio

<em>Moles -Masa molar Ti: 47.867g/mol-:</em>

2.36g de Titanio * (1mol / 47.867g) =

<h3>0.0493 moles de Titanio</h3>
