Continuous Assessment 1 Study Guide Flashcards

Vocabulary flashcards covering unit conversions, density, atomic structure, isotopic abundance, periodic trends, clinical applications, and study guide formulas for Continuous Assessment 1.

Fahrenheit to Celsius Conversion Formula

$$^\circ\text{C} = \frac{^\circ\text{F} - 32}{1.8}$$

Celsius to Fahrenheit Conversion Formula

$$^\circ\text{F} = 1.8(^\circ\text{C}) + 32$$

Density Formulas

$d = \frac{m}{V}$, $m = dV$, and $V = \frac{m}{d}$

Mass Number Formula

$$\text{Mass number } A = \text{protons} + \text{neutrons}$$

Neutrons Formula

$$\text{neutrons} = \text{mass number} - \text{atomic number}$$

Ion Charge Formula

$$\text{charge} = \text{protons} - \text{electrons}$$

Neutral Atom Electron Relationship

$$\text{electrons} = \text{protons} = \text{atomic number}$$

Average Atomic Mass Formula

$$\sum [(\text{fractional abundance})(\text{isotope mass})]$$

Percent Abundance to Fraction Formula

$$\text{fraction} = \frac{\text{percent}}{100}$$

Atomic-Mass Conversion Factor

$$1\,\text{amu} = 1.66 \times 10^{-24}\,\text{g}$$

Infusion Time Formula

$$\text{time} = \frac{\text{total volume}}{\text{flow rate}}$$

Total Amount from Concentration Formula

$$\text{amount} = \left(\frac{\text{amount}}{\text{reference volume}}\right)\left(\frac{\text{total volume}}{\text{reference volume}}\right)$$

Main-Group Valence Electrons Reminder

Group 1 elements have $1$ valence electron; Group 2 elements have $2$ valence electrons.

Ionization Energy Periodic Trend

1st ionization energy generally increases across a period and decreases down a group.

Period vs. Group

A period is a horizontal row on the periodic table; a group is a vertical column whose elements have the same number of valence electrons and similar chemical behavior.

1st Ionization Energy

The energy required to remove the first electron from an atom.

Clinical Drug Amount Practice Problem

For a medication containing $250\,\text{mg}$ of drug per $100\,\text{mL}$, a patient receiving $300\,\text{mL}$ receives $750\,\text{mg}$ of drug.

Clinical Drug Mass from Percent Practice Problem

For a medication with density $1.00\,\text{g/mL}$ and $0.25\%$ drug by mass, a patient receiving $300\,\text{mL}$ receives $750\,\text{mg}$ of drug.

Assessment Structure Guidelines

Questions 1–2 require identifying equations and keeping units; Question 3 requires writing 2–3 needed relationships before calculating; Questions 4–5 require evaluating statements I–IV as true or false.
