HO

2 compounds have this formula on CompoundList.

Molar mass: 17.01g/mol
Monoisotopic mass: 18.0090Da
Atoms: 2
Elements: 2

The formula HO describes a molecule made of 1 hydrogen atom and 1 oxygen atom. It is written in Hill notation: with no carbon present, every element is listed in alphabetical order. The formula tells you which atoms are present, not how they are connected, which is why several different chemicals can share it.

Elemental composition

H Hydrogen × 15.93%
1.008 × 1 = 1.008 g/mol
O Oxygen × 194.07%
15.999 × 1 = 15.999 g/mol
