Calculate the molar mass of SiO2, show your work by entering the atomic mass in the proper boxes.

Molar mass of SiO2 = ...?
g/mol Si + 2 * ...?
g/mol O = ...?
g/mol SiO2 (total)

Answer 1

The way you have it written is correct, you just need to find the values of mass on the periodic table. For Oxygen, it'd be around 15.99g/mol

Answer 2

Answer:

The molar mass of SiO2 =  60.0835 g/mol

Explanation:

The molar mass of the compound silicon oxide(SiO2) can be calculated from the sum of the atomic mass of the atoms.

SiO2 compounds contains 2 different atoms namely silicon and oxygen. The silicon is 1 atom while the Oxygen is 2 atom.

Atomic mass of Si = 28.0855 g/mol

Atomic mass of O = 15.999 g/mol

Mass for 2 atom of O = 15. 999 × 2 = 31.998 g

The molar mass of SiO2 =  28.0855 + 15.999 × 2

The molar mass of SiO2 =  28.0855 + 31.998

The molar mass of SiO2 =  60.0835 g/mol
