Will silicon sink or float in water?

Silicon will sink in water because it has a higher density than water.


Compute the density of an 820g sample of pure silicon occupying a 350cm3 container?

Density is calculated as mass divided by volume. In this case, the mass of the silicon sample is 820g and the volume of the container is 350 cm^3. Therefore, the density of the silicon sample in the container is 820g / 350 cm^3 = 2.34 g/cm^3.


Why is the density of silicon less than carbon?

The density of an element is determined by its atomic mass and atomic structure. Silicon has a larger atomic mass compared to carbon, but its atomic structure is less compact, leading to a lower density. Silicon atoms are larger and have more space between them, resulting in a lower mass per unit volume compared to carbon. This difference in atomic structure and arrangement contributes to the lower density of silicon compared to carbon.


What is the density of a chunk of silicon weighing 8.763 was placed in a graduated cylinder containing 25.00 of water the water level in the cylinder rose to 28.76?

Mass of silicon = 8.763 (grams? tons?) Volume of silicon = 28.76 - 25.00 (cc? cubic meters?) = ..... Density = Mass of silicon divided by Volume of silicon. = ....... gms/cc? tons/cubic-metre?


Which layer of the earth is made up of low density materials such as oxygen silicon and aluminum?

The Earth's crust is made up of low-density materials such as oxygen, silicon, and aluminum. This layer is divided into two parts: the continental crust, which is thicker and less dense than the oceanic crust.
