What is the purpose of constructing a calibration curve in GC analysis?

A spectrum with aromatic bands ~1600/1500 cm^-1 AND a strong carbonyl ~1715 cm^-1 most strongly suggests:Reference spectrum provided for this question.

The broad band from 3000–2500 cm⁻¹ in acids is due to _______________ O–H stretching.

The experiment requires unknown injections in triplicate at ______ µL to compute %RSD.

A “Match Factor > 90 %” in library search implies:

A systematic increase in residuals from low → high concentration suggests possible ________ (e.g., nonlinearity or saturation).

You observe the blank after the high standard shows a small dodecane peak (~3% of the low standard). Best interpretation?

_________ fibers are characterized by a strong ester carbonyl near 1735 cm⁻¹.

If a tablet contains [X] mol CaCO₃, how many mol HCl can it neutralize? (Report to 4 decimal places)

In FTIR, __________ spectra account for ambient water and CO₂.
