1) Convert 45.0 cm³ to L.

2) Acetone (CH₃COCH₃) has a density of .791g/mL. Assuming this compound is soluble in water, how many grams are present in 3.0 L of acetone. If acetone was spilled in Furman Lake, what would you expect to see and how would this be classified in the matter scheme (element,compound, heterogeneous, or homogeneous mixture?

3) Convert the distance from Sacramento to Modesto, CA. The measured length of the trip is approximately 121 kilometers. Convert this distance to meters and miles.

4) In January, the average temperature of eastern Siberia is -50°C. Calculate this temperature in Fahrenheit and Kelvin. Of the three temperature units, which one is the SI unit for temperature.

5) The mass of an adult human eyeball is 7.5 grams. Convert this value to kilograms and ounces. What type of lab equipment is used to measure mass?

6) How many milliliters and gallons are contained in a 2.0L Coca-Cola drink? (1 gallon = 3.79 L)

7) Convert your body temperature to °F and K.

8) Your cat needs .5 tsp of Tylenol. How many milliliters is this dosage?

9) The density of lead is 11.3g/mL. If you measured out .92 kg, how many milliliters would this mass displace? Based upon density only, would you expect lead to sink or float in water?

10) If you have a body temperature of 35°C, are you hypothermic or hyperthermic?
