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.
Ok so firstly you need to determine the number of moles of calcium carbonate that reacts If you look at the periodic table or using your memory you can determine the molar mass of calcium carbonate. So here's what you want: n = m/M. n = mols. m = mass.M = molar mass.o the molar mass of CaCO3 is 40.1 + 12.0 + 3(16.0). =100.1 g/mol. Finding n: n = m/M. n = 10.1/100.1 n = 0.100 mol of calcium carbonate (CaCO3). Next you look at the equation. CaCO3(s) â CaO(s) + CO2(g) You can read it like: For every 1 mol of CaCO3 that reacts you produce 1 mol of CaO and 1 mol of CO2.
