Answer:
The type of bond between the Oxygen atom and the hydrogen is Covalent
this is because the 2 electrons are being shared by both hydrogen and oxygen 
The type of bond this molecule makes as a whole is called a Hydrogen Bond
A hydrogen bond is formed because of the partial +ve and -ve charge in a molecule
The cause of the partial +ve and -ve charge is the comparatively high electronegativity of oxygen which makes the electron get attracted towards the oxygen atom while the hydrogens try to maintain the maximum distance from the lone pairs due to repulsion

The concentration of the hydrogen ions from molarity can be given with the number of hydrogen atoms in the molecular formula.
<h3>What is molarity?</h3>
Molarity is given as the moles of the solute present in a liters of solution. The compound with the number of hydrogen atoms in the molecular formula with degradation possesses the equivalent concentration of the hydrogen ions.
The compound with molecular formula AH having molarity 2, will produce 2M of hydrogen ions.
