Why silicon oxide is solid and carbon dioxide is gaseous in nature?

It contains only single bond betweenSilicon and Oxygen. Also SiO2 has a covalent bonded network structure which makes it solid and having high melting point. ... Because CO2 forms discrete molecules with one carbonatom bonded to two oxygen atoms.

It is because of the structure of the CO2COX2. Two of carbon's valence electrons hybridize into two spsp hybrid orbitals. As a result, the molecule is one dimensional with an angle of 180∘∘ between bonds and completely non-polar. The SiSi, on the other hand, does not form such bonds and the angle is far from 180°, which in conjunction with oxygens high electronegativity makes it quite polar. Thus the interaction between neighboring SiSi and OO atoms of different SiO2SiOX2molecules is much higher and as a consequence you need much more energy to break the solid, giving it an increased melting point.
The mass (as discussed in various comments) does not play any role here since it is a matter of interaction or forces. The gravitational pull of single atoms or molecules is ridiculously small and never finds any considerations in such calculations (as it should!).
