From the given chemical formula we conclude that

The stoichiometry of magnesium and silicon is 3 : 2

3 moles of magnesium is equivalent to 2 moles of silicon

9.62 moles of magnesium will be equivalent to \frac{2}{3}\times 9.62=6.41 moles of silicon

Therefore, the number of silicon present in sample are 6.41 moles.
