When an irregularly shaped chunk of silicon weighing 8.763 $\mathrm{g}$ was placed in a graduated cylinder containing 25.00 $\mathrm{mL}$ of water, the water level in the cylinder rose to 28.76 $\mathrm{mL}$ . What is the density of silicon in $\mathrm{g} / \mathrm{cm}^{3} ?$

Key Concepts

Density

Density is a fundamental property of matter that describes the mass of a substance per unit volume. It is calculated by dividing the mass by the volume, and it helps distinguish materials based on how compactly their mass is distributed. Understanding density is essential for comparing material properties and for applications in fields such as physics, chemistry, and engineering.

Water Displacement Method

The water displacement method is a technique used to measure the volume of an irregularly shaped object. When the object is fully submerged in water, the rise in water level corresponds to the object's volume due to the principle that an object immersed in a fluid displaces a volume of fluid equal to its own volume. This method is especially useful when the object’s shape makes it difficult to measure dimensions directly.
