The molarity of her solution will be 1.88 M

<h3>What is Molarity ?</h3>

Molarity is defined as the number of moles of solute dissolved in per litre of solution.

Molarity of the solution = number of moles of solute / volume of solution in litre

number of moles of solute = given weight / molecular weight

                                            = 43.3 / 45.95

                                            = 0.942 moles

Now, lets calculate Molarity ;

Molarity of the solution = number of moles of solute / volume of solution in litre

                                       = 0.942 / 0.500

                                       = 1.88 M

Hence, The molarity of her solution will be 1.88 M

Which of the following species has the greatest
Licemer1 [7]

Answer: Option (3) is the correct answer.

Explanation:

When there is a negative charge on an atom then we add the charge with the number of electrons. Whereas when there is a positive charge on an atom then we subtract the charge from the number of electrons.

Atomic number of chlorine is 17. So, number of electrons present in Cl^{-} is 17 + 1 = 18 electrons.

Atomic number of cobalt is 27. So, number of electrons present in Co^{4+} is 27 - 4 = 23 electrons.

Atomic number of iron is 26. So, number of electrons present in Fe^{2+} is 26 - 2 = 24 electrons.

Atomic number of vanadium is 23. So, number of electrons present in V is 23 electrons.

Atomic number of scandium is 21. So, number of electrons present in Sc^{2-} is 21 + 2 = 23 electrons.

Thus, we can conclude that out of the given species, Fe^{2+} has the greatest  number of electrons.
