Yes. In the chemical formula H2O, the subscript 2 after the hydrogen means there are two hydrogen atoms in a molecule of water. The absence of a subscript after the oxygen means the subscript is understood to be 1, so there is one atom of oxygen in a water molecule.
CO2, (note 2 is subscript and denotes that there is 2 oxygen atoms in the molecule.)
A symbol for a diatomic molecule as N2 (2 is a subscript, impossible to write in WA).
The subscript that is to the right of the element symbol, no subscript means 1. Example H2O, 2 hydrogen 1 oxygen
1.What number represents the coeffcient 5H2? 2.What does the corffcient 5H2?
H(subscript 2)O
there are two atoms in the molecule

there are two atoms in the molecule
The subscript 2 shows the number of oxygen atoms in each molecule of the compound, carbon dioxide.
CO2, (note 2 is subscript and denotes that there is 2 oxygen atoms in the molecule.)
In chemical formulas, a subscript number signifies the number of atoms of the specified element in a molecule. For example, H2O (where the "2" is subscript) is the formula for water and represents 2 hydrogen atoms combined with 1 atom of oxygen.
usually a subscript denotes the number of atoms of a particular element within the formula. ie H2O (the 2 would be a subscript) indicates there are two atoms of hydrogen in one molecule of water.
Because symbols for the elements do not have subscripts. A subscript is added in the chemical formula of a compound to indicate how many atoms of the element are included in a molecule of the compound. For example, when hydrogen (H) and oxygen (O) combine to form water (H2O), a subscript 2 is added to the H to indicate there are two hydrogen atoms in a molecule of water, but no subscript is added to the O, because there is only one oxygen atom is in a molecule of water.
The number in the subscript of a chemical formula tells the number of that atom in a molecule. For example, in H2O, the 2 tells you there are 2 hydrogen atoms in the water molecule. in C3H8, there are 3 carbon atoms and 8 hydrogen atoms as reflected by the 3 and 8 in the formula respectively.
The formula of an oxygen molecule is O2 (2 is a subscript but now WA doesn't permit to write a subscript).15.9994 g/mol is the molecular mass of oxygen. Formula mass is a sum of atomic mass of atoms in the molecule. In O2 there are two oxygen so it will be about 32g/mol
The subscript refers to the number of the specific atom or, if parentheses are present, group of atoms, in a molecule or formula unit. No subscript is given if there is only one such atom per molecule. For example, H2O is the formula for water. the subscripted 2 shows that there are two hydrogen atoms in the molecule.
