At a local pawn shop a student finds a medallion that the shop owner insists is pure platinum. However, the student suspects that the medallion may actually be silver or aluminum, which are much less valuable. The student buys the medallion only after the shop owner agrees to refund the price if the medallion is returned within two days. The student, a chemistry major, then takes the medallion to her lab and measures its density as follows. She first weighs the medallion and finds its mass to be 55.64 g. She then places some water in a graduated cylinder and reads the volume as 75.2 mL. Next she drops the medallion into the cylinder and reads the new volume as 77.8 mL. Is the medallion platinum (density = 21.4 g/cm³), silver (density = 10.5 g/cm³), or aluminum (density = 2.70 g/cm³)? WHERE ARE WE GOING? What information do we need to determine the identity of the medallion? (Select all that apply.) the density of possible metals the mass of the medallion the volume of the medallion the shape of the medallion the cost of the medallion

The shattered glass case at the scene of a jewelry store robbery was determined to be made of potash borosilicate glass, which has a density of 2.162g/mL. A 4.034g glass fragment was recovered from a suspect's clothing. When the fragment was placed into a graduated cylinder filled with water, 1.63mL of the water was displaced. Calculate the density of the glass fragment.
A student finds that 24.96 g of water at 24.9 C(density=0.9971 g/cm3) is required to completly fill an empty flask. The water is removed and completely dried; granular solid copper weighing 51.24g is then added to the flask. With the copper present in the flask, it was determined that 19.24 g of water was required to fill the remaining space in the flask completly 1.) volume of the empty flask 2.) volume of the copper 3.) density of the copper
A student weighed their penny (mass = 2.499 g) and followed the same experimental procedure you did in the lab. They found that the penny contained 0.0980 g of copper, or, 3.92%. Estimate the thickness of the copper coating with the following formula. From the US Mint website: the diameter of a penny is 19.05 mm and the thickness is 1.52 mm. The density of copper is 8.96 g/cm3. TIP: your final answer will have the units of cm (think about what to do first.). mass of Cu volume density of Cu Thickness of Cu Coating = area (diameter 2 T T (diameter) (thickness) O 7.39 x 104 cm O 1.65 x 103 cm O 4.22 x 102 cm O 2.80 x 103 cm O 1.89 x 105 cm O impossible to determine
Ammonium phosphate NH43PO4 is an important ingredient in many fertilizers. It can be made by reacting phosphoric acid H3PO4 with ammonia NH3 . What mass of ammonium phosphate is produced by the reaction of 2.07g of phosphoric acid? Be sure your answer has the correct number of significant digits.
4. Given the density of Au is 19.3 g/cm3, determine the mass of gold in an ingot having a volume of 0.015 m3.

1. In the olden days, US minted pennies were pure copper, but copper got so expensive that a pure copper penny was worth more than I cent. Modern pennies are composed of zinc and coated with copper. A student determines the mass of a penny to be 2.482 g. After making several scratches in a penny, the student puts the penny into hydrochloric acid, where the zinc (but not the copper) reacts with hydrochloric acid via a single replacement reaction. The hydrogen is collected at 25°C over water. The collected gas occupies 0.899 L at a total pressure of 791 mm Hg. A. Calculate the moles of hydrogen produced in the reaction. (Hint: Use the Table 1. to determine the vapor pressure of water and assume that all of the zinc in the penny dissolves.) B. Write a balanced chemical reaction for zinc and hydrochloric acid. C. Use stoichiometry to calculate the mass of zinc in the penny. D. Determine the percent zinc (by mass) in the penny.

CHEMISTRY Calculating Density Density is the compactness of matter. Density describes the quantity of matter (mass) per unit of volume (3-dimensional space). Density is calculated as the mass of the matter divided by volume. The symbol for density is Greek letter rho (p). The units for mass are in grams (g) and the units for volume is cubic centimeter (cm³). It should be noted that 1 cm³ is equal to 1 ml of volume. 1 cm³= 1 ml. The units for density are g/cm³. Part 1 Determine the density of the new liquid materials created in the Secret Density Research Laboratory. Type the value (no units) of the density into the boxes in the density column. Report density to the 2nd number after the decimal. Use a zero to the lef of the decimal for values less than 1.00.

In the United States, car fuel efficiency is expressed in miles per gallon of gasoline. However, fuel efficiency can also be expressed in kilometers per liter of gasoline. If the fuel efficiency of a car is 11.0 km/L, what is its fuel efficiency in miles per gallon? [1 mile = 1.61 km, 1 gallon = 3.79 L]
1. A student weighs an empty special round bottom flask and stopper. He finds the mass to be 56.972 g. He then adds about 5 mL of an unknown liquid and heats the flask in a boiling water bath at 100°C. He allows all the liquid to vaporized and then removes the flask from the bath, stoppers it, and lets it cool. Upon cooling, he briefly removes the stopper, then replaces it and weighs the flask and condensed vapor, obtaining a mass of 57.917 g. The volume of the flask is known to be 240.2 mL. The barometric pressure in the laboratory that day is 743 mm Hg. What was the pressure of the vapor in the flask in atm? O 0.9776 atm 0.98 atm 0.978 atm 0.977 atm
