Question

Now, provide the following information: Molecular formula

Answer 1

The molecular

Step-by-step explanation:

Molecular formula consists of the chemical symbols for the constituent elements followed by numeric subscripts. The numeric subscripts only tell us the number of atoms of the constituent elements

$\begin{gathered} _{}_{}_{}_{} \\ \text{ Molecular formula of water} \\ H_2O\text{ } \\ \text{The constistuent elements are hydrogen and oxygen} \\ \text{Water has 2 atoms of hydrogen and 1 atom of oxygen} \end{gathered}$

Molecular mass of water can be calculated as follows

H2O

The molar mass of hydrogen is 1

The molar mass of oxygen is 16

Since water has two atoms of hydrogen and 1 atom of oxygen

Molecular mass of water = 2(1) + 1(16)

Molecular mass of water = 2 + 16

Molecular mass of water = 18g/mol

Hence, the molecular mass of water is 18g/mol
