WebThe molar mass of chlorine is 35.5 grams per mole, and calcium, 40 grams per mole. CaCl2 is calcium chloride, so we want to work out how many grams of calcium chloride contain 15.0 grams of chlorine. Let’s call the unknown mass of calcium chloride 𝑥. The ratio between the chlorine mass and the calcium chloride mass is fixed. WebCorrect option is D) Molecular weight of CaCl 2=111g/mol. Ions in one calcium chloride molecule = Ca +2+2Cl − = 3 ions. Now no. of molecules in 111g/mol of CaCl 2 = Avogadro's number. = 6.02×10 23 molecules. So number of ions in 111g/mol of CaCl 2=3×6.02×10 23 ions =3 moles. Was this answer helpful?
