Low-grade copper ore contains a small amount of copper (1% or lower) and a big amount of waste rock. The problem with low-grade copper is that it breaks down and melts more easily than copper ore.
What mass of copper oxide will be obtained by heating 12.35gm of copper carbonate?
The easiest way to solve these problems is to use what is called a unit multiplier. First begin with the number of grams of copper that you have, then use the unit multiplier that expresses the number of grams per mole of copper (this is the number that corresponds to the atomic mass on the periodic table times grams, divided by moles). Then use the number of copper atoms that it takes to create copper oxide; this will depend on the oxidation state of the copper. Finally it reverse the process by adding up the atomic masses of copper oxide, and that will be the number of grams per mole of copper oxide, returning you from Moles back to Grams.

Can you run copper pipes inside concrete slab?
It can be done and it has been done plenty in the past. However, with the advent of pex, no prudent journeyman would embed copper in concrete. The risks of copper failing are greater than those of PEX. Potential copper problems are calcification inside the pipe and corrosion due to ingredients such as lime, etc. in the concrete.
