A cylindrical bar was found at the bottom of a storage tank of unknown composition. The material had a diameter of 8 mm, a length of 62 cm and a mass of 0.018 kg. What is the density of this material in g/mL? The volume of a cylinder is given by V = πr^2h.
A manufacturer of paint claims that a gallon (3.78L) 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. You may use the following conversions: 12 in = 1 ft, 2.54 = 1 in
The German chemist Fritz Haber proposed paying off the reparations imposed against Germany after World War I by extracting gold from seawater. Given the following data, what was the dollar amount of the gold that could have been extracted from 3.0 m3 of seawater? The price of gold at the time was $0.68 per gram of gold. Gold occurs in seawater to the extent of 5.15 x 1011 atoms per gram of seawater. The density of seawater is 1.03 g/cm3.
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?
What is the density (in g/mL) of a cube that has equal sides of 12 inches and weighs 491 pounds? The volume of a cube can be calculated by: lxwxh. Which metal is it considering the following densities: Cu: 8.96g/cm3, Al: 2.70g/cm3, Fe: 7.87g/cm3 and Zn: 7.13g/cm3?
The average micro-nano plastic concentration in bottled water was about 2.4×10^5 particles per liter of bottled water, about 90% of which were nano-sized particles. Assuming that each nanoparticle can be approximated as a sphere with a diameter of 100 nm and that the average density of nanoparticles is 1.2 g/cm^3, estimate the mass of nanoparticles ingested if someone drinks all of their recommended 64 fluid ounces of water per day via bottled water every day for a year. Provide your answer is units of nanograms (ng).

A motorcycle’s fuel tank has a capacity of 0.0221 kL and the motorcycle can travel 15.0 km/L. 1. How many liters of fuel would be needed to travel 62.4 km? 2. How long of a trip, in kilometers, can be made on one tank of gasoline? 3. If the density of gasoline is 0.738 g/mL, what is the mass (in grams) of the fuel in the tank when it is full? 4. When 1.00 g of gasoline burns, 4.70 kJ of energy is released. Based on your answer for question 3, how many kilojoules are produced when the fuel in one full tank is burned? Write your answer in scientific notation.
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.)
