Answer:
The answer to How many moles of silicon are in 245 g of silicon? is:
a. 8.72 mol
Explanation:
To resolve this problem, we need to know the Silicon atomic weight, we can find this information in the periodic table of elements
\(Si= 28.0855 \frac{g}{mol}\)
This means that for every mole, there are 28.0855 grams of Silicon
Now, with this information we can find the answer to this problem:
\(245 g*\frac{1 mol}{28.0855 g} = 8.72 mol of Silicon\)
