What is the formula mass of SiO2?

Answer 1

60.086 amu

> It's not very helpful simply stating the answer.

The relative Atomic Mass of 1 silicon (Si) atom = 28.1

For Oxygen (O) = 16.0.

The calculation is:

28.1 + (16.0 x 2) = 60.1 g

(1 mol of an atom = relative atomic mass in grams)

Answer 2

I believe the more common term is molar mass and is calculated like so:

In one molecule of SiO2 there are two Oxygen (O) atoms and one Silicon (Si) atom.

To calculate the molar mass simply add the atomic masses of each atom present together. The atomic mass of each element can be found on the Periodic Table.

The atomic mass of Si is 28.0855 g

The atomic mass of O is 15.9994 g

Since there are two O atoms in one molecule of SiO2 the calculation will be:

(15.9994 x 2) + 28.0855 = 60.0843

The molar mass of SiO2 is 60.0843 g

Answer 3

atomic mass for Si is 28,0855 u.

Answer 4

The gram molecular mass of silicon dioxide is 60.08. Multiplication gives the mass of 3.50 moles as 210.3 grams, to the justified number of significant digits.

Answer 5

Three, one silicon and two oxygen.

Answer 6

Three

Answer 7
