The mass of sodium (in mg) consumed is to be calculated. Concept Introduction: Solutions are homogeneous mixtures made up of two components, the solute and the solvent. The same solutes and solvents can form a number of combinations by varying their amounts. These combinations can be differentiated in terms of concentration of solutions. Concentration of a solution is defined as the amount of solute present in the given amount of solvent. There are many ways of expressing concentration of a solution, such as mass percent, volume percent, molarity, parts per million. Mass percent is defined as the mass of solute present in 100 g of a solution. Volume percent is defined as the mass of solute present in 100 mL of a solution. Parts per million is defined as the mass of solute present in 10 6 g of a solution. It is used for expressing concentration when a small amount of solute is present in the solution. Density = Mass of water (g) Volume of water (L) It is known 1 g = 1000 mg , conversion factor is as 1000 mg 1 g

Interpretation Introduction

Interpretation:

The mass of sodium (in mg) consumed is to be calculated.

Concept Introduction:

Solutions are homogeneous mixtures made up of two components, the solute and the solvent.

The same solutes and solvents can form a number of combinations by varying their amounts. These combinations can be differentiated in terms of concentration of solutions. Concentration of a solution is defined as the amount of solute present in the given amount of solvent.

There are many ways of expressing concentration of a solution, such as mass percent, volume percent, molarity, parts per million.

Mass percent is defined as the mass of solute present in 100 g of a solution.

Volume percent is defined as the mass of solute present in 100 mL of a solution.

Parts per million is defined as the mass of solute present in 106 g of a solution. It is used for expressing concentration when a small amount of solute is present in the solution.

Density = Mass of water (g)Volume of water (L)

It is known 1 g = 1000 mg, conversion factor is as 1000 mg1 g

Show that a molecule with configuration π4 has a cylindrically symmetric electron distribution. Hint: Let the π orbitals be equal to xf and yf, where f is a function that depends only on the distance from the internuclear axis.

(a) Verify that the lattice energies of the alkali metal iodides are inversely proportional to the distances between the ions in MI (M = alkali metal) by plotting the lattice energies given below against the internuclear distances dMI. Is the correlation good? Would a better fit be obtained by plotting the lattice energies as a function of (1 — d*/d)/d, as theoretically suggested, with d* = 34.5 pm? You must use a standard graphing program to plot the graph. It generates an equation for the line and calculates a correlation coefficient. (b) From the graph obtained in (a), estimate the lattice energy of silver iodide. (c) Compare the results of (b) with the experimental value of 886 kJ/mol. If they do not agree, explain the deviation.
