How to Balance an equation
(s) is for solid, (l) is for liquid, and (g) is for gas.
CaO (s) + CO₂ (g) ----> CaCo₃ (s)
IUPAC Naming
CO2= Carbon Dioxide
Molar Mass
CO₂= 44.01 g/mol
To find the molar mass, you take the atomic weight and multiply it by how many it has.
Converting mole to mole
Example. If you have 11.30 Moles of CaO and you're trying to figure out how many moles of CaCo₃ you have.
Take the given (11.3 mols) than multiply it by the mol ratio, in this case that means you have 11.30 moles of CaCo₃
Mass to Mass
Follow the steps from mole to mole conversions, however, you must divide your second substance by your first substance with a value of 1.
For example,
4.13 grams of Co₂ will convert to 9.39 grams of CaCo₃
After the mole conversion, you would do 100.086 grams CaCo₃ over 1 mole of Co₂
