Verified Answer :

The molar mass of SiH4 (Silicon Hydrogen) is approximately 32.117 grams per mole, SIH4 has a mass of 298.69 grams of course.

Answer:

298.716 g of \(SiH_{4}\)

Explanation:

\(SiH_{4}\) 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 \(SiH_{4}\) will be:

Molar mass of \(SiH_{4}\) = 28.0855 + (1.00784 x 4)

Molar mass of \(SiH_{4}\) = \(32.12\frac{g}{mol}\)

it means that one mol of \(SiH_{4}\) has a molar mass of \(32.12\frac{g}{mol}\).

Now you can calulate the mass:

\(9.30molesSiH_{4}*\frac{32.12gSiH_{4}}{1molSiH_{4}}\) = 298.716 g of \(SiH_{4}\)
