According to Data,
                             Mass Number  =  65

                             # of Neutrons  =  35

As we know,
                             Mass Number  =  # of protons + # of Neutrons
Solving for # of protons,
                                # of protons  =  Mass Number - # of Neutrons
Putting values,
                                # of Protons  =  65 -35

                                # of protons  =  30
As, 

# of protons is the atomic number, so element with atomic number 30 is Zinc.

The cation derived from it has 28 electrons,
So, Zinc having 30 electron will be left with two extra protons, and each proton has +1 charge.

Result:
                                                    Zn

If 45 mL of water are added to 250 mL of a 0.75 M K2SO4 solution, what will the molarity of the diluted solution be?
krok68 [10]

Answer:

\large\boxed{\large\boxed{0.64M}}

Explanation:

When you form a <em>diluted solution</em> from a mother (concentrated) solution, the moles of solute are determined by the mother solution.

The main equation is:

Molarity=\dfrac{\text{moles of solute}}{\text{volume of the solution in liters}}

Then, since the moles of solute is the same for both the mother solution and the diluted solution:

          \text{Molarity mother solution }\times\text{ volume mother solution}=\\\\=\text{Molarity diluted solution }\times\text{ volume diluted solution}

Substitute and solve for the molarity of the diluted solution:

           250mL\times 0.75M=(45mL+250mL)\times M\\\\\\M=\dfrac{250mL\times 0.75M}{295mL}=0.64M
