The interrogative adjectives introduce questions about identity, definition, selection, or quantity and always appear before the noun they modify. Adjectives helps to understand their function because these forms describe or specify a name within the sentence. What questions the nature or definition of something, while which points to a choice among already possible or known options. In more formal registers, what is used more for definition and which for selection.
How Much functions as an interrogative adjective when it accompanies a noun and agrees with it in gender and number. Its form can be cuƔnto, cuƔnta, cuƔntos o cuƔntas, according to the noun it modifies, and the same concordance also serves in exclamations. Adjectives Quantitativos and Adjetivos Numerales show why this relationship with the noun is essential to express quantity with precision.

What, which and how much carry a tilde when introducing direct questions, indirect questions and exclamations. That tilde distinguishes them from relative or exclamative non-interrogative forms that appear in other contexts. In combined questions, the form adapts to the noun and to the number, such as what movie, which of the movies or how many tickets.
What identifies or defines, which selects among options and how much asks about quantity with gender and number agreement. All these forms are placed before the noun they modify and carry the tilde in questions and exclamations. Their exact value depends on whether the question seeks definition, choice or measure, and on whether an explicit noun appears or not.
