Question

Calculate the number of mole of cacl2 calcium chloride that can be obtained frm 30g of calcium trioxocarbonate iv in the presence of excess hydrochloride acid
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.
Is the answer correct
