The London Dispersion force s a temporary attractive
force that results when the electrons in two adjacent atoms occupy positions
that make the atoms form temporary dipoles. And because of this, the London
Dispersion force is considered to be the weakest intermolecular force.
Answer:
2.38x10²³ atoms oxygen
Explanation:
To solve this question we need to convert the mass of sand to moles using its molar mass (Molar mass SiO₂ = 60.08g/mol). Twice these moles are the moles of Oxygen and using Avogadro's number we can find the amount of atoms of Oxygen in the mixture:
<em>Moles SiO₂:</em>
11.87g * (1mol / 60.08g) = 0.1976moles SiO₂
<em>Moles Oxygen:</em>
0.1976moles SiO₂* 2 = 0.3951moles oxygen
<em>Atoms oxygen:</em>
0.3951moles oxygen * (6.022x10²³atoms / 1mol O₂) =
<h3>2.38x10²³ atoms oxygen</h3>
