Answer: Democritus
Explanation: Democritus was a Greek philosopher who was the first person to use the term atom(atomos: meaning indivisible). He thought that if you take a piece of matter and divide it and continue to divide it you will eventually come to a point where you could not divide it any more. This fundamental or basicunit was what Democritus called an atom.
The density of zinc is 7.16 g/ml.
Density can be calculated by the formula -
Density =
In the given question, the volume of given mass of mossy zinc can be found by finding change in volume of water.
Change in volume = new volume - original volume
Change in volume = 54.6 - 50.0
Performing subtraction to find the change in volume
Change in volume = 4.6 ml
Now, keeping the values in formula to find the density of given mass of mossy zinc.
Density =
Performing division to find the density of given mass of mossy zinc
Density = 7.16 g/ml
Hence, the density of mossy zinc is 7.16 g/ml.
