Pyramids were built in Ancient Egypt as tombs, or burial places, for Egyptian pharaohs, or kings. They believed that the pyramids made you immortal. The Ancient Egyptians believed in an afterlife, so it was very important to them to protect the bodies of their pharaohs.
CaCO3, or calcium carbonate, has a molar mass of 100.09 grams per mole. This means there are roughly 566 grams of CaCO3.
The molecular formula is C13H18O2, so; 13.5 grams C13H18O2 (1mole C13H18O2/206.274 grams)(13 mole C/1 mole C13H18O2) = 0.8508 moles of carbon 0.8508 mole C (12.01 gra â¦ ms/ 1 mole C) = 10.2 grams of carbon (reasonable, as carbon is most of this product).o figure out the number of grams in one mole of a substance, you need to calculate the molecular weight of the substance. This is done by adding the atomic weight of each ATOM in the molecule.
