Measurement Madness

Mrs. Ismert's dog pickles has a mass of 40,823.3 g and a volume of 4200 mL. How dense is the big boi in correct significant figures?

9.7 g/mL

200

Mrs. Ismert's other dog, Nacho has a volume of 2025 mL and a mass of 22679.6 g. Is he more or less dense than Pickles (7.1 g/mL?)

More dense! 11.20 g/mL, short and stout

Mr. Jochem's favorite highlighter weighs 15 g.  He needs to find the volume. He starts with 110.0 mL of water and drops the highlighter in. The new volume in his graduated cylinder is 116.2 mL. What is the volume of his favorite highlighter?

6.2 mL

Mrs. Ferraro picked up a dozen donuts for the science department. When she got to school and opened the box, there were only 10 donuts. What is the percent error of the donut shop?

20%

In the lab, you determine the density of a slug of aluminum to be 2.45 g/mL. Your chemistry book states that the density of aluminum is 2.70 g/mL. Calculate your percent error.

9.26%

At the zoo, a zoologist weighs an otter and finds her density to be 56.1 g/mL. An average otter's denisty if 59.45 g/mL.  How far off is this otter from normal?

5.7%

You decide to determine the weight of a tall iced caramel machiatto with extra carmel drizzle. Starbucks lists on their website that this drink should weigh 60 grams.  You take Mrs. Ismert's coffee and weigh it, finding it is 47 grams. What percent did she get ripped off?

20%

This living animal has the heaviest brain (African Bush Elephant, Black Rhinoceros, Human, Sperm Whale)

This type of water weighs the most (seawater, distilled water, tap water, none they all have the same weight)

Sea water! It is loaded with mineral salts and weights about 1.5 pounds more per cubic foot than freshwater at the same temperature
