Answer:
298.716 g of [tex]SiH_{4}[/tex]
Explanation:
[tex]SiH_{4}[/tex] is a molecule with one atom of Si and four atoms of H.
First you should calculate the molar mass of each atom:
Molar mass of Si = 28.0855
Molar mass of H = 1.00784
So, the molar mass of the [tex]SiH_{4}[/tex] will be:
Molar mass of [tex]SiH_{4}[/tex] = 28.0855 + (1.00784 x 4)
Molar mass of [tex]SiH_{4}[/tex] = [tex]32.12\frac{g}{mol}[/tex]
it means that one mol of [tex]SiH_{4}[/tex] has a molar mass of [tex]32.12\frac{g}{mol}[/tex].
Now you can calulate the mass:
[tex]9.30molesSiH_{4}*\frac{32.12gSiH_{4}}{1molSiH_{4}}[/tex] = 298.716 g of [tex]SiH_{4}[/tex]
