Fluorite is harder than gypsum but softer than apatite. Thus, the correct option is B.
<h3>What is the hardness of any element?</h3>
The hardness of any element may be defined as the capability of a material to oppose the process of deformation and remains in actual shape precisely.
According to the table of hardness scales by Mohs, the increasing order of given hardness of given elements is as follows:
Gypsum < Fluorite < Apatite.
Therefore, Fluorite is harder than gypsum but softer than apatite. Thus, the correct option is B.

Answer:
The sphere on the left has the most inertia because it has more mass.
Explanation:
Inertia is a property of matter of a substance.
According to Newton's first law of motion, a body continues to stay in the state of rest or constant velocity unless acted upon a external force.
The amount of inertia that an object possess is proportional to the mass of the object.
The sphere on the left is of 300 kg and that on the right is of 30 kg.
Clearly, the sphere on the left has more mass.
Therefore, the sphere on the left has the most inertia.
Answer: 
iron atoms
Explanation:
According to avogadro's law, 1 mole of every substance weighs equal to the molecular mass and contains avogadro's number 
of particles.
![1 molecule of [tex]Fe_2O_3](https://tex.z-dn.net/?f=1%20molecule%20of%20%5Btex%5DFe_2O_3)
contains= 2 atoms of iron
![1 mole of [tex]Fe_2O_3](https://tex.z-dn.net/?f=1%20mole%20of%20%5Btex%5DFe_2O_3)
contains=
atoms of iron
thus 0.32 moles of 
contains=
atoms of iron
Thus the sample would have iron atoms.
