Density is defined as mass per unit volume.
the mass of 1 mL of CO₂ is - 0.0019 g
3.5 L = 3500 mL
then the mass of 3500 mL of CO₂ is - 0.0019 g/mL x 3500 mL = 6.65 g
mass of 3.5 L of CO₂ is 6.65 g
the mass of 1 mL of CO₂ is - 0.0019 g
3.5 L = 3500 mL
then the mass of 3500 mL of CO₂ is - 0.0019 g/mL x 3500 mL = 6.65 g
mass of 3.5 L of CO₂ is 6.65 g
Answer : The pH of the solution is, 1.31
Explanation : Given,
Mass of = 248 mg = 0.248 g (1 mg = 0.001 g)
Volume of solution = 140 mL
Molar mass of = 36.5 g/mole
First we have to calculate the concentration of hydrochloric acid.
Molarity : It is defined as the number of moles of solute present in one liter of volume of solution.
Formula used :
Now put all the given values in this formula, we get:
The concentration of HCl is, 0.0485 M
As we know that, HCl dissociates to give hydrogen ion and chloride ion.
The dissociation reaction is:
Concentration of HCl = Concentration of H⁺ = Concentration of Cl⁻ = 0.0485 M
Now we have to calculate the pH of the solution.
pH : It is defined as the negative logarithm of hydrogen ion concentration.
Mathematically,
Therefore, the pH of the solution is, 1.31
