It isn't easy


concentrated and diluted have not a quantitative meaning, but essentially qualitative, especially diluted.
When You say that HCl is concentrated You generally intend that It is about 36% in weight (12 M) that is the maxime concentration that you can industrially obtain with chemical absorption.
But for HNO3 concentrated is about 67% (azeotrope of distillation, 14 M), so for H2SO4 aboit 96% (18 M).
For a salt, it may be the condition of saturation, that is about 260 g/L for NaCl, but for other salts it changes very much when you change the temperature.
When you speak of diluited, you have added some water in these solutions, but it isn't specified how much
