Write your detailed solution starting with the identification of the given quantities.  You purchase a rectangular piece of metal that has dimensions 5 x 15 x 30 mm  and mass 0.0158 kg. The seller tells you that the metal is gold. To check this, you  compute the average density of the piece. What value do you get? Were you  cheated

A cylindrical storage tank has a radius of 1.06 m. When filled to a height of 3.67 m, it holds 12600 kg of a liquid industrial solvent. What is the density of the solvent? Number i Units

The hydraulic diameter of a rectangular duct is calculated using the equation D = 4, where Dr is the hydraulic diameter, A is the cross-sectional area of the duct and p is the perimeter of the duct. If the dimensions of the rectangular duct are a = 26 cm+0.4 mm, and b = 33 cm +1.3 mm, what is the uncertainty of D, in percentage format? Enter the answer as a numerical value without any sign. Retain 3 significant figures. a

The material that holds the world record for being the least dense solid is silica aerogel, with a density of only 1 mg/cm3. What would be the mass of a cube of silica aerogel that measured 1 m on each side?   Can you show me step by step how to do this? I know that Density=mass*volume

A full can of soda has a mass of 0.436 kg. It contains 3.40 x 104 m³ of liquid. Assuming that the soda has the same density as water, find the volume of aluminum used to make the can. Number i Units

A group of students wish to determine, experimentally, the bulk density of an unknown material. To determine this amount, the students measured the diameter, height, and mass of various cylinders. These values ​​appear in the table below. Determine: a) The volume of the cylinders that appears in the following table. b) The graph of mass vs. volume.

The Statue of Liberty in New York City is approximately 305 ft305 ft tall. How many U.S. dimes would be in a stack of the same height? Each dime is 1.35 mm1.35 mm thick. number of dimes:     Each dime has a mass of 2.268 g.2.268 g. How much would the stack of dimes from the previous question weigh? mass:   g What is the value, in dollars, of the same stack of dimes? value:   dollars The 2017 U.S. gross domestic product (GDP) was valued at 19,390,604,000 dollars.19,390,604,000 dollars. How many Statue of Liberty‑height stacks of dimes are needed to match the GDP in value? number of stacks:

What is the volume of a hat box (cylinder) in liters, which is 60.0cm in diameter and 38.5cmtall ? (V = πr2h) Explain how you got your answer.

A large tank is filled to capacity with 500 gallons of pure water. Brine containing 2 pounds of salt per gallon is pumped into the tank at a rate of 5 gal/min. The well-mixed solution is pumped out at the same rate. a) Find the number A(t) of pounds of salt in the tank at time t. b) what is the concentration c(t) of the salt in the tank at time t? At t=5 min? What is the concentration of the salt in the tank after a long time (we can this concentration the limiting value), that is, as t→--? At what time is the concentration of the salt in the tank equal to one-half this limiting value? 500 gallons
