But we have only 0.19 mol HCl (aq), hence, HCl (aq) is limiting reagent. So amount of CaCl2 formed will depend on the amount of HCl available. Since, 2 mol HCl (aq) forms 1 mol of CaCl2, therefore, 0.19 mol of HCl (aq) would give: Please log in or register to add a comment. ← Prev Question Next Question →.

Molecular mass or molar mass are used in stoichiometry calculations in chemistry. In related terms, another unit of mass often used is Dalton (Da) or unified atomic mass unit (u) when describing atomic masses and molecular masses. It is defined to be 1/12 of the mass of one atom of carbon-12 and in older works is also abbreviated as "amu".

The first thing to do here is to calculate the relative formula mass of CaCO 3 and CO 2. RFM of CaCO 3 = 40 g + 12 g + (16 g x 3) = 100 g. RFM of CO 2 = 12 g + (16 g x 2) = 44 g. The decomposition equation shows 1 CaCO 3 goes to 1 CaO and 1 CO 2. We have 50 g of CaCO 3, effectively we have half a CaCO 3. 50 g / 100 g = 0.5
