**Transcription for Educational Use:**

Atomic absorption spectroscopy was used to determine the amount of aluminum in a sample of sunscreen. A blank solution was measured seven times to determine the detection and quantitation limits of the spectrometer. The blank readings were: 0.0073, 0.0082, 0.0110, 0.0101, 0.0102, 0.0098, and 0.0090 AU. Determine the signal at the detection limit and the signal at the limit of quantitation for this method.

- **Signal detection limit:** [Input box]

- **Signal limit of quantitation:** [Input box]

**Explanations:**

- This text is providing the setup and task for a laboratory experiment focused on measuring aluminum content using atomic absorption spectroscopy.
- The detection limit refers to the smallest signal that can be reliably distinguished from a blank (non-signal) sample.
- The quantitation limit is the lowest signal level at which a particular analyte can be quantitatively detected with suitable precision and accuracy.

The lithium concentration in serum taken from a patient being treated with lithium for manic-depressive illness was analyzed using flame emission spectroscopy. A sample of the serum gave a reading of 283 units for the intensity of the 671 nm red emission line. Then, 1.00 mL of a 11.5 mM lithium standard was added to 9.00 mL of serum. This spiked serum gave an intensity reading of 633 units at the 671 nm emission line. What is the original concentration of Lit in the serum?

A student needs to prepare a ¹H NMR sample for an organic compound soluble in chloroform (CHCI3). The student cannot use CHCI 3 as the solvent for the sample, but rather uses deuterated chloroform (CDC13) because: O CDC13 is more polar. O CDC13 will not produce a signal in the ¹H NMR spectrum, and therefore will not mask the signals of the compound. O The compound will be more soluble in CDCI 3. O CDC13 is cheaper than CHCI 3.
