Silicon Carbide (SiC) - Unleashing the Power of Silicon Composition
What is the percent composition of silicon in silicon carbide (SiC)?
70% is the percent composition of silicon in silicon carbide (SiC). Given:Si has a molar mass of 28.09 g/mole. C has a molar mass of 12 g/mole. SiC's molecular weight is 40.09 g/mole (28.09 g + 12 g).
Answer:
The percent composition of silicon in the compound silicon carbide is approximately 70%. The silicon has an atomic mass of 28 g. Atomic mass of C (Carbon atom) = 12 g. Silicon Carbide total mass = 28 + 12 = 40 g. Using the formula: Silicon mass divided by the compound's total mass yields a composition percentage of 100%. = 28/40 × 100% = 70%. Therefore, the silicon content in SiC is 70%.
