CALCULATE THE NUMBER OF MOLE CALCIUM CLORIDE THAT CAN BE OBTAINED FROM 30g OF CALCIUMTRIOXO CARBONATE (4) IN THE PRESENCE OF EXCESS HYDROCLORIC ACID
First I must tell you that calcium trioxonitrate (4) is not a correct name for CaCO3 (or anything else). Several names are acceptable by IUPAC for CaCO3 but that name is not one of them. Calcium carbonate is an acceptable name by IUPAC. Please tell me what book that came from. Please let me know how you were told to name it that. If this was a teacher that told you that let him/her know it just isn't correct. For the problem,
CaCO3 + 2HCl ==> CaCl2 + H2O + CO2
mols CaCO3 = grams/molar mass = 30/100 = 0.30 mols. Looking at the equation, it tells you that you get 1 mol CaCl2 for every 1 mol CaCO3; therefore you will get 0.30 mols CaCl2.
