All answers must use the correct number of significant figures, and must show
units!
1. (2 points) SHOW ALL WORK. A 34.6 g bar of aluminum occupies 12.8 mL.
Calculate the density of aluminum.
2. (2 points) “A 3 g sample of calcium (an electrically conducting white metal that is
shiny, relatively soft, melts at 850 °C, and boils at 1440 °C) was placed into 1.0 L of
water at 25 °C. The calcium reacted slowly with the water to give bubbles of gaseous
hydrogen and a solution of the substance calcium hydroxide.” In this description, what
physical properties (name 3) and what chemical properties (name 1) are described?
3. (4 points) SHOW ALL WORK. A 2.00 g sample of zinc oxide (contains only zinc
and oxygen) contains 1.61 g of zinc. What mass of oxygen would be contained in a
sample that weighs 4.75 g?
4. (2 points) Fill in the blanks.
1 Tg = _______ g
1 L = ________ L
1 Mm = ________ m
1 fL = ________ L
5. (4 points) SHOW ALL WORK. Convert 136 °F to K.
5. (5 points) SHOW ALL WORK. The recommended adult dose of ubiquotracin is 3.75
mg/kg of body mass. Calculate the dose in mg for a 142-lb person.
