Answer:
6.00 moles of sodium permanganate
Explanation:
Let us attempt to count the number of atoms present in sodium perchlorate. The formula of the compound is NaClO4
Sodium atoms - 1
Chlorine atoms - 1
Oxygen atoms -4
Total number of atoms = 6
Among the options, only KMnO4 also has six atoms. One atom of potassium, one atom of manganese and four atoms of oxygen.
Molarity and normality are the ways of expressing concentration which includes the volume of the solution.
As we know,
Molarity is defined as the number of moles of solute dissolved in 1L of the solution. Thus,
M = no. of moles of solution/ Volume of solution on litres.
while, Normality is the number of gram equivalents of the solute dissolved per litre of the solution.
N = Gram equivalent of the solute/ volume of solution in litres.
while, the other concentration expressing terms such as mole fraction, molality includes the mass of the solution and solvent respectively.

I feel like it's C. or D. but I guess it's C.
When the neutrons and electrons are the same. For example, sodium (Na) has an atomic mass of 11, meaning it has 11 protons and 11 electrons etc.
