CHAPTER 2^

Calculations

At the end of each method, described in the preceding chapters, factors and formulas are given for calculating the results, and specific examples are calculated. In this chapter some general formulas are given and the factors are collected into tables, one for the gravimetric (Table 4 0 ) and one for the volumetric (Table 4 1 ) . There is included a table of multiples of atomic and molecular weights (Table 4 2 ) which is useful for calculating percentages in empirical formulas.* There are also included discussions on the calculation of factors and on the calculation of percentages from the empirical formula and vice versa. The chapter is concluded with two sets of logarithmic tables.

The first of these, Table 43, the Nitrogen Reduction T a b l e ,9-1 0 gives the logarithms of the weight of one ml. of nitrogen at the various temperatures and pressures encountered in the laboratory and is used for calculating the results of the Dumas nitrogen determination. The second, Table 44, is a regular table of five-place logarithms.

* The atomic weights proposed by the Commission on Atomic Weights of the I.U.P.A.C., 1957,6 have been used throughout. Tables showing the percentage composi­

tion of many organic compounds have been published by Gysel3 and by Kuffner and Gruber.7 Thompson1 2 described a calculator for selection of sample weights in the microdetermination of carbon and hydrogen.

Calculation of Factors11

Factors, such as given in Tables 40 and 41, usually are found in the various books on analytical chemistry2'1 3 and in the handbooks.4'5-8 However, the author believes that an understanding of their methods of calculation is in order since it allows the analyst to calculate factors if the particular ones desired are not listed. The following examples will serve the purpose.

GRAVIMETRIC:

Examples:

a. From the equations given in Chapter 20, it is seen that one methyl group attached to nitrogen is equivalent to one molecule of silver iodide

Now in 1 ml. of 0.01N thiosulfate there are 1.58114 mg. of N a2S203 .*. M . W . of C H3 : M . W . of 6 N a2S203 : : χ : 1.58114

where χ = mg. of C H3 .*. 15.035 : 948.684 : χ : 1.58114 15.035 X 1.58114 r f ^τ τ

Calculation of Percentages from the Empirical Formula and Vice Versa

For many of the samples analyzed the empirical formulas are known and the theoretical values of each element may be calculated. This is accomplished by use of the following formula:

Theoretical per cent of the element =

At. wt. of element X no. of these elements present X 100 M.W. c f compound

Likewise, for groups, the following is used:

Theoretical per cent of the group =

Sum of at. wts. of elements in group X no. of these groups present X 100 M . W . of compound

(5)

569 Percentages

Example:

The percentages of carbon, hydrogen, and carboxyl in benzoic acid, C6H5C O O H , are obtained by

7 V 1ΠΠ

= 6 8 . 8 5 % C

= 4 . 9 5 % H 12.011 X 7 X 100

122.125 1.008 X 6 X 100

122.125 45.019 X 1 X 100

122.125 and

4 v m o ν 1 ν 1 on

= 3 6 . 8 6 % COOH

On the other hand, for many of the samples the empirical formulas are not known and must be calculated from the found values. The method of calculation given here1 1 is that discussed in detail by Clark.1 For an example, suppose the elementary analyses of a compound showed it to have the fol­

lowing percentages of carbon, hydrogen, and oxygen:

C = 5 8 . 7 2 % H = 5 . 9 2 % Ο = 3 5 . 3 6 % Therefore, in 100 grams of substance there are

58.72 grams C 5.92 grams Η 35.36 grams Ο

The atomic weights of the three elements are, respectively, 12.011, 1.008, and 16.000 and if these are called grams, 100 grams of the above compound contains

58.72 12.011

5.92 1.008 35.36

= 4.89 units of C

= 5.87 units of Η

= 2.21 units of Ο 16.000

Therefore, the compound contains carbon, hydrogen, and oxygen in the proportion of 4.89 to 5.87 to 2.21 units respectively. By dividing these three values by that of the smallest, namely, 2.21, the proportion becomes 2.21 units of carbon to 2.66 units of hydrogen to 1 unit of oxygen. Whole num­

bers are required and in this case it is not possible to see on inspection what factor is necessary to use in order to have all three come out whole numbers.

Therefore, Table 39 is set up in which all of the values in the proportion 2.21 units of C:2.66 units of H : l unit of 0 are multiplied by 1, 2, 3, 4, etc.

Before any attempt is made to select a series in which all of the numbers are closest to being whole, the rule concerning the composition of molecules with elements having odd valences must be considered. The number of elements in a molecule having odd valences must be equal to an even number. This must be true since carbon is tetravalent. This rule eliminates immediately each of the series in which the hydrogen is closest to odd numbers and only those closest to the even ones should be considered, namely, ( c ) , ( f ) , ( i ) , and ( 1 ) . Of this group ( i ) has both of the values for C and Η closest to whole numbers.

Consequently, the empirical formula is C2o H24 09 which has the theoretical values of carbon, hydrogen, and oxygen equal to the following

C = 5 8 . 8 2 % , Η = 5.92%, Ο = 3 5 . 2 6 %

which are in excellent agreement with the found figures.

Other data such as the values obtained from carboxyl (neutralization equivalent), methoxyl, acetyl, molecular weight, etc., are helpful in selecting the proper empirical formula.
