The chemical formula for snow is the same as for water: H₂O. Snow is simply water in solid form, made of ice crystals composed of water molecules arranged in a crystalline lattice.
Basic formula
Snow consists of individual ice crystals, and each ice crystal is made of water molecules with the formula H₂O. The change from liquid water to snow only alters the physical state and structure, not the chemical formula.
Structure of snow
In snow, water molecules are arranged in a hexagonal ice crystal lattice, which gives snowflakes their characteristic six-fold symmetry. This ordered structure is why snow has distinct crystal shapes while remaining chemically identical to liquid water as H₂O.
