The number of grains of brown sand in the bucket is 76000 grains

Data obtained from the question

From the question given above, the following data were obtained:

  • Total grain of sand in the bucket = 9.5 billion = 9.5×10⁹
  • Concentration of brown sand = 8 ppm = 8 / 1000000
  • Amount of brown sand =?

How to determine the amount of brown sand

The amount of brown sand in the bucket can be obtained as illustrated below:

Amount = concentration × total

Amount of brown sand = (8 / 1000000) × 9.5×10⁹

Amount of brown sand = 76000 grains

Thus, the number of grains of brown sand in the bucket is 76000 grains
