In a vessel filled to the brim with water, a number of balls with a volume of 4 * 10 to -9 degrees was lowered. At the same time, the volume of water flowed out of the vessel was 1 ml. How many balls were dropped into the water?

To find out the number of balls pubescent in the indicated vessel, consider the formula: Nx = V / Vsh1, where V is the total volume of the balls, the volume of outflowed water (V = 1 ml = 10-6 m3); Vsh1 – the volume of each ball (Vsh1 = 4 * 10-9 m3).

Let’s calculate: Nx = V / Vsh1 = 10-6 / (4 * 10-9) = 250 balls.

Answer: 250 balls should have been lowered into the water.
