The wight of `HCl` present in one litre of solution if `pH of the solution is one

The weight of HCl present in one litre of solution, if pH of the solution is one :

0.4 g of NaOH present in one litre solution shows the pH :

0.4g of NaOH is present in one litre of the solution shows that H^(+) concentration of the solution is

When 10^(-6) mole of a monobasic strong acid is dissolved in one litre of solvent, the pH of the solution is ..............

When 10^(-6) mole of a monobasic strong acid is dissolved in one litre of solvent, the pH of the solution is ..............

When 10^(-6) mole of a monobasic strong acid is dissolved in one litre of solvent, the pH of the solution is ..............

The concentrations of solutions are also expressed in Demal units. One demal unit represents one mole of solute present in one litre of the solution at
