· Copper is found alongside many other types of ore. It can be found near gold, silver, zinc, lead, and other types of metal deposits. When mixed in with other ores, copper is not usually found in great abundance. Until the development of the modern copper mining process, it was typically a byproduct of mining for other metals.
Introduction to Chemistry
The percent abundance of 14 C is so low that it can be ignored in this calculation. The average atomic mass of carbon is then calculated as (0.9889 × 12 amu) + (0.0111 × 13.003355 amu) = 12.01 amu. Carbon is predominantly 12 C, so its average atomic mass should be close to 12 amu, which is in agreement with our calculation.
