It is also given in the question that one pH unit represents the 10 fold change in the concentration of hydrogen ion.
Now for lemon juice whose pH is 2, hydrogen ion concentration is equal to

And for pure water whose pH is
, hydrogen ion concentration is equal to

Thus, the H+ ion concentration in lemon juice is
times greater than the pure water.
