AP Biology Pretest - Kasha Maslowski | Biblioteka

Instrukcije

Answer the following questions. Your performance has no bearing on your belonging to the AP Biology community, all skill levels are welcome! This test only serves as a diagnostic of your current skills and will be used to create a tailored plan for your studies over the summer.

If you are unsure of your answer or would like your individualized plan to include more support on any given question, just mark "I do not know / I have little confidence". Remember, this is not an entrance test, but a test designed to help you get ready for AP Biology!

I can't wait for our journey to begin!

To convert 5 kilometers to meters, which of the following setups is correct? (You are not expected to memorize conversions. Let's just practice setting up conversion factors!)

5 \text{ km} \times \frac{1000 \text{ m}}{1 \text{ km}}

5 \text{ km} \times \frac{1 \text{ km}}{1000 \text{ m}}

5 \text{ km} \times \frac{1 \text{ m}}{1000 \text{ km}}

1 \text{ km} \times \frac{100 \text{ m}}{5 \text{ km}}

How many molecules are in 1 gram of a substance with a molar mass of 18 g/mol? Use Avogadro's number, 6.022 \times 10^{23} molecules/mole, to help with your calculations. Which of the following setups is correct? (You will not be asked to do stoichiometry in AP Biology. Let's just practice setting up conversion factors!)

1g \times \frac{1 \text{mole}}{18g} \times \frac{6.022 \times 10^{23} \text{molecules}}{1 \text{mole}}

1g \times \frac{6.022 \times 10^{23} \text{molecules}}{1 \text{mole}} \times \frac{1 \text{mole}}{18g}

1g \times \frac{1 \text{mole}}{6.022 \times 10^{23} \text{molecules}} \times \frac{18g}{1 \text{mole}}
