Exciting Discovery: Percent Composition of Silicon in Silicon Carbide

What is the percent composition of silicon in silicon carbide (SiC)?

A. 28% B. 50% C. 70% D. 142%

Answer:

C. 70%

If you're curious about the exciting world of chemistry, you'll be thrilled to learn about the percent composition of silicon in silicon carbide (SiC)!

Silicon carbide is a fascinating compound that consists of silicon and carbon. But do you know what percentage of silicon makes up silicon carbide?

Well, the answer is 70%! That's right, 70% of silicon carbide is made up of silicon. This composition is determined by calculating the mass of silicon compared to the total mass of the compound.

Let's break it down further. The atomic mass of silicon is 28 g, and the atomic mass of carbon is 12 g. When combined, the total mass of silicon carbide is 40 g. By using the formula for percent composition, which is Mass of the silicon/Total mass of the compound × 100 %, we find that the percent composition of silicon in silicon carbide is 70%.

So, when you think about silicon carbide, remember that it's comprised of 70% silicon, making it a truly remarkable compound with unique properties and applications.
