Suppose some measurements are made on two different homogeneous stones to find out if they are made of the same kind of rock. The mass and volume measurements are listed below. Are the two stones the same type of rock? Why or why not? Show all calculations.

Gold can be hammered into extremely thin sheets called gold leaf. A 200-mg piece of gold (density = 19.32 g/cm3) is hammered into a sheet measuring 2.4 ft x 1.0 ft. %3D What is the average thickness of the sheet in meters? Hints: Calculate the volume of the sheet from its density and mass, and then use the volume relationship for a rectangular solid, V = length x width x thickness.
I think I did a calculation wrong but I am having trouble understanding significant figures. In this problem, I am calculation the density of water from my previous calculations mass= 7.359g and volume=7.8mL. So I then divided 7.359g by 7.8mL to find density and got (.9434615385) on my calculator which I then turned into (.94) because I believe there should be 2 significant figures. Is (.94) correct or should 1.4 be the final answer?
- 5 A chemist adds 405.0 mL of a 8.16 x 10 mM zinc oxalate (ZnC,04) solution to a reaction flask. Calculate the mass in micrograms of zinc oxalate the chemist has added to the flask. Be sure your answer has the correct number of significant digits. u g x10
What answer should be reported, with the correct number of significant figures, for the following calculation? (249.362 + 41.0) / 63.498 O 4.57277 O 4.5728 O 4.573 O 4.57 O 4.6
An electric current of 481.0 mA transports 530. uC of charge. Calculate the time this took. Be sure your answer has the correct unit symbol and 3 significant digits. 0 x10 X H 8 S
If a sample of gold alloy has a mass of 87.7 g and is 78.3% gold by mass, what percentage of the alloy is made up of other metals? Write your answer to the nearest tenth of a percent. (I had to alter the wording of this question since it wasn't calculating significant figures properly, so if you got it wrong because of significant figures you can assume you probably actually got it correct.)
Perform the following calculations to the correct number of significant figures. [(2.33 x 10^6) / 42.370] + 132.99
To prepare a solution of NaCI, you weigh out 2.634 (to.002) g and dissolve it in a volumetric flask whose volume is 100.00 (±o.08) mL. Express the molarity of the solution, along with its uncertainty, with an appropriate number of digits.
A manufacturer of paint claims that a gallon (3.78 L) of latex paint can cover 365 ft2 of the surface of a wall in a single coating. The paint manufacturer also claims that one single coating of an entire wall will be 3.40 mm thick. Is this a case of false advertising? Yes or No? Elaborate your answer by providing a calculation (handwritten, upload a pdf). You may use the following conversions: 12 in = 1 ft, 2.54 cm = 1 in
