TABLE 114.-Brix, apparent density, apparent specific gravity, and grams of sucrose per 100 ml of sugar solutions

Column 1 gives Brix or percentage of sucrose in the solution.

Column 2 gives apparent density, that is, the weight in air with brass weights of 1 ml of solution at 20° C. The values in this column correspond to the values of true density (table 113), having been obtained by means of the formula

which may be utilized for converting apparent density into true density, and vice versa, by considering that M, the weight in vacuo, and W, the apparent weight, refer to 1 ml, since true density is defined as the weight in vacuo of 1 ml, and the apparent density as the weight of 1 ml of substance in air with brass weights. is the density of air, which has been taken as 0.0012046;2 d, the density of the solution, d2 the density of the weights, which has been taken as 8.4.

Column 3 gives the apparent specific gravity at 20° C. The values in this column were obtained by dividing the apparent density in column 2 by the apparent density of water at 20° C., which was taken as 0.997174.3

Column 4 gives the grams sucrose (weighed in vacuo) per 100 ml of solution. The values in the table were calculated in three sections by different individuals; thus from 40 to 60 Brix by Peters and Phelps (BS Tech. Paper T338, 1927); 60 to 83.9 Brix by Brewster and Phelps (NBS Research Paper RP536, 1933); and the remaining values, 0 to 40 and 84 to 95 Brix by Snyder, Saunders, and Golden of this Bureau. After the computations were completed, the tabulations were made by rounding off the values to the last figure given. The values are considered exact to 1 in the fifth decimal.

The apparent Brix, that is, grams of sucrose dry substance per 100 g of solution, weighed with brass weights in air, is approximately 0.01 percent greater than the true Brix in column 1.
