WebThe density of the 10.0% solution is 1.109 g/mL. Answer PROBLEM 8.3.4 The hardness of water (hardness count) is usually expressed in parts per million (by mass) of CaCO 3, which is equivalent to milligrams of CaCO 3 per liter of water. What is the molar concentration of Ca 2+ ions in a water sample with a hardness count of 175 mg CaCO 3 /L? Answer WebThere are two chloride ions in copper chloride, CuCl 2 There must be 2 × (3.7 × 10–3) mol of chloride ions present, i.e. 7.4 × 10–3 mol (= 0.0074 mol) 20 –136.55 g of carbon = 36.55 g/12.01 g mol = 3.043 mol of carbon 1 mole of carbon contains 6.02 × 1023 atoms of carbon Therefore 3.043 moles of carbon contain
