/// Modul Larutan
/// Solution Module
/// Menghitung molaritas larutan (M) dari jumlah mol (n) dan volume larutan (V).
/// Calculates solution molarity (M) from the number of moles (n) and solution volume (V).
/// Rumus: M = n / V
/// Formula: M = n / V
/// Menghitung pH larutan asam kuat dari konsentrasi ion hidrogen [H+].
/// Calculates pH of strong acid solution from hydrogen ion concentration [H+].
/// Rumus: pH = -log[H+]
/// Formula: pH = -log[H+]
