Answer: The mass percent of silicon in the given compound is 15.9 %
Explanation:
We are given:
A chemical compound having chemical formula [tex]BaCuSi_2O_6[/tex]
To calculate the percent by mass of silicon in given compound, we use the equation:
[tex]\text{Mass percent of Silicon}=\frac{\text{Mass of silicon}}{\text{Mass of compound}}\times 100[/tex]
Mass of silicon = [tex](2\times 28)=56.2g[/tex]
Mass of compound = [tex][137.33+63.55+(2\times 28.1)+(6\times 16)]=353.08g[/tex]
Putting values in above equation, we get:
[tex]\text{Mass percent of silicon}=\frac{56.2}{353.8}\times 100\\\\\text{Mass percent of silicon}=15.9\%[/tex]
Hence, the mass percent of silicon in the given compound is 15.9 %
