What is the mass of 9.30 moles of sih4 ?

298.716 g of

Explanation:

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 will be:

Molar mass of = 28.0855 + (1.00784 x 4)

Molar mass of =

it means that one mol of has a molar mass of .

Now you can calulate the mass:

= 298.716 g of

i don,t know so just answer mine
