Given information

Concentration of solution of   (by mass) is   %

Density of the solution is g/mL . 

 

Step-by-step explanation

Step 1.

Let us assume that the total weight of solution of  is g

The mass percentage of is % . It is expressed as:

% of mass =  

Molecular mass of HNO3 is g/mol

Number of moles  =  

Number of moles of  = moles

Also, Density of the solution is g/mL

Convert volume of solution ( g) from gram to liters. 

g of solution =    

We determine the concentration of 

Molarity =  

Molarity =  

Substituting all the values, we calculate concentration in molarity

Concentration = M  

The concentration i.e.   is same as the acid given.

 

we know that, 

Dissociation constant of water (Kw) =   

Also,
