83.3 mL

Explanation:

M_{i} = 3M

V_{i} = 50mL

M_{f} = 1.80M

Unknown:

V_{f} = ?

Solution:

To solve this problem we must understand that the initial and final number of moles remains the same.

  Number of moles = molarity x volume

Molarity x volume of initial solution = Molarity x volume of final solution

 Therefore:

   M_{i}  x  V_{i}     = M_{f} x   V_{f}

M is the molarity

V is the volume

i = initial state

f = final state

    input the parameters;

  3 x 50 = 1.8 x V_{f}

      V_{f} = 83.3 mL

It takes energy to ionize any atom. It takes progressively more and more energy for each successive electron that is removed and
IrinaVladis [17]

Answer:

Removal of Third Electron

Explanation:

a major jump is required to remove the third electron. In general, successive ionization energies always increase because each subsequent electron is being pulled away from an increasingly more positive ion.

Ionization energy increases from bottom to top within a group, and increases from left to right within a period.

A compound is found to contain 23.3% magnesium, 30.7% sulfur and 46.0% oxygen. What is the empirical formula of this compound?
Nesterboy [21]
Answer:

MgSO_3

Explanation:

As is standard for these sorts of questions, we assume 100 g of substance, and use the percentage elemental compositions to calculate an empirical formula.

"Magnesium" = (23.3*g)/(24.31*g*mol^-1) = 0.958*mol

"Sulfur" = (30.7*g)/(32.06*g*mol^-1) = 0.958*mol

"Oxygen" = (46.0*g)/(15.999*g*mol^-1) = 2.86*mol

We divide thru by the smallest molar quantity (0.958*mol) to get and empirical formula of MgSO_3, magnesium sulfite.

Ordinarily you would not be given the percentage of oxygen by mass. You would be given the percentages of the metal and sulfur, and would have to assume that the balance was oxygen.


Hope this helps!
