The Power of 70%: Understanding Silicon Carbide Composition

The percentage composition of silicon in the given compound is 70% (Option C). To determine the percent composition of silicon in silicon carbide (SiC), we need to calculate the mass of silicon in the compound relative to the total mass of the compound.

Silicon carbide is a compound consisting of silicon and carbon atoms. Understanding the percent composition of silicon in silicon carbide is crucial in various industrial applications.

The molar mass of SiC can be calculated by adding the atomic masses of silicon and carbon. It approximately equals 40.0962 g/mol.

To determine the percent composition of silicon, we divide the molar mass of silicon by the molar mass of SiC and multiply by 100%. The result is approximately 70%, indicating the dominance of silicon in silicon carbide.

Therefore, knowing that silicon constitutes 70% of silicon carbide highlights its significance in the compound's properties and functions.
