Number of atoms in 1.4 mol of Phosphorus trifluoride (PF₃) : 8.428 x 10²³
<h3>Further explanation </h3>
The mole is the number of particles(molecules, atoms, ions) contained in a substance
1 mol = 6.02.10²³ particles
Can be formulated
N=n x No
N = number of particles
n = mol
No = Avogadro's = 6.02.10²³
1.4 mol of Phosphorus trifluoride (PF₃), number of atoms :
The earth is divided into "spheres", each with its own properties and characteristics. The sphere containing all of the solid ground and layers of the earth is known as the lithosphere (or geosphere).
Other spheres of the earth are the hydrosphere, the cryosphere, and the atmosphere.
Answer:
this option is correct the amount of heat required to turn a mole of a solid into a liquid
it's the last one because it's depended on the rock layers
