Answer

Explanation:

Step1: Find molar - mass of silicon

From the periodic table, the molar - mass of silicon (Si) is approximately 28.09 g/mol.

Step2: Calculate moles of silicon

Use the formula $n=\frac{m}{M}$, where $n$ is the number of moles, $m$ is the mass, and $M$ is the molar - mass. Given $m = 662.7$ g and $M=28.09$ g/mol, then $n=\frac{662.7}{28.09}$. $n = 23.6$ mol (rounded to 3 significant figures)

Answer:

23.6
