Hep me out guys
The correct IUPAC name for that weird trioxo name is calcium carbonate.
CaCO3 + 2HCl ==> CaCl2 + H2O + CO2
How many mols CaCO3 do you have to start? That's mols = grams/molar mass = 30/100 = 0.30. How many mols CaCl2 will that form? That's 0.3 mols CaCO3 x (1 mol CaCl2/1 mol CaCO3) = 0.30 mols CaCl2.
