Chromatography
To find the weight of the same number of marbles as the glass beads, we first need to find the weight of one glass bead in grams (320 mg = 0.32 g). Then we divide the total weight of the glass beads by the weight of one glass bead to determine the number of glass beads. Finally, we multiply this number by the weight of one marble (8.58 g) to find the total weight of the marbles. In this case, the same number of marbles would weigh 0.32 * 5.13 kg / 8.58 g each = 1.92 kg.
A technique called chromatography or a technique called filtration could be used to separate the red and blue marbles. chromatography would depend on the differences in solubility between the red and blue marbles, while filtration would depend on differences in size or density between the marbles.

There are 8/9 black beads and the same amount of white beads in the anime. But in the manga, the beads are RED and white. I don't know if there is the same amount of beads in the manga as there are in the anime.
You can separate silver beads from sugar beads by using a magnet to attract the silver beads, as they are often made of materials that are attracted to magnets. This will leave the sugar beads behind. Alternatively, you can dissolve the sugar beads in water, as sugar is soluble in water, while the silver beads will remain intact.

Going of weight of real hama beads there should be about 16000 beads but that is only if the weigh the same.

In order for 4 red marbles to be one-third of a group and 3 blue marbles to make up one-fourth of the same group the number has to equal 12.
