Prove a new penny is not made of pure copper It has a mass of 2.49 and a volume of 0.349cm3?
at first, you have to find the density of the penny. [density = mass/ volume ] so 2.49/ 0.349 = 7.1347. rounded to 7.1 but the density of the copper is 8.92 g/ cm3 as the densities are not close, the penny is not pure copper. hope this help :)
How do you calculate the mass of 14.5 moles of copper?
1 mole of Copper has a mass of 63.546 g. So, 14.5 moles will be 14.5 times that amount. Do the math.
Is copper wire a mechanical mixture?
It should be a "pure" substance, but its really an alloy.
Is copper sulfate a pure substance?
Pure:CuSO4(H2O)5
How do you make pure copper?
You make pure copper through electrolysis this is the link that helped me:http://science.jrank.org/pages/1781/Copper-Making-pure-copper.html
Calculate the mass of 0139 moles of copper?
Mass = moles x formula mass Mass = 0.139 x atomic mass of copper (63.5) Mass = 8.83g
What is the mass in g of pure copper ore metal?
It depends how much of it you have.
calculate the mass of copper that could be made from 4.0g of copper oxide?
I think 3.55 grams
What is the atomic mass of copper and zinc?
The density of pure copper is: 8.94 g/cm^3 The density of pure zinc is: 7.13 g/cm^3
Calculate the average atomic mass of copper-63 and copper-65?
63.6166 Relative abundance of Copper-63 is 69.17% and Copper-65 is 30.83%

Copper is a transition element used in the making of coins calculate the mass in grams of 0.0420 moles of copper?
The atomic mass of copper is 63.55 g/mol therfore 0.043 moles weighs 2.67 g
How much does 3 inch diameter 20foot long copper pipe weigh?
Pipes are normally hollow so, while the given information is sufficient to calculate the mass of a copper rod, you need to know either the thickness of the copper of the inner and outer diameters to calculate the nmass of the pipe. You also need the density of the material but since the pipe is made of a pure element, that information is readily available.
