Sig. Figs Question #1
A) A graduated cylinder contains 18.0 mL of water. What is the new water level after 35.6 g of silver metal with a density of 10.5 g/mL is submerged in the water?
B) How many cubic centimeters (cm3) of olive oil have the same mass as 1.00 L of gasoline? density: olive oil = 0.92 g/mL, gasoline = 0.66 g/mL
c) The area of a triangle is 67.4 in2. Convert this area to cm2. (1 inch = 2.54 cm)
D) A train is traveling at 78.4 miles per hour. Convert this velocity to hectometers per min. Use the following conversions: 1 inch = 2.54 cm, 60 min = 1 hour, 1 mile = 5280 ft, 1 ft = 12 inch

A graduated cylinder contains 16.5 mL of water. What is the new water level after 39.4 g of silver metal with a density of 10,5 g/mL is submerged in the water? Express your answer using three significant figures. Part B A thermometer containing 7.4 g of mercury has broken. If mercury has a density of 13.6 g/mL, what volume spilled? Express your answer using two significant figures.

When boiling water, a hot plate takes an average of 7 minutes (min) and 16 seconds [s] to boil 150 milliliters [ml] of water. Assume the temperature in the lab is 78 degrees Fahrenheit (°F). The hot plate is rated to provide 379 watts [W]. If we wish to boil 150 milliliters (ml) of acetone using this same hot plate, how long do we expect the process to take? Acetone has a boiling point of 56 degrees Celsius [°C]. [Hint:...

The herbicide dichlobenil (2,6-dichlorobenzonitrile, C7H3Cl2N) has a solubility of 18.0 mg/L by mass in water at 20 ∘C. The herbicide disintegrates with a half-life (first order) of 1.00 year. Suppose that 323 kg of dichlobenil is applied in the fields surrounding a 7.50-acre pond having an average depth of 3.00 ft. Suppose further that half of the dichlobenil permeates into the pond and that this happens within a few days. Assume that the density of the pond water is 1.00...
