To study a marine organism, a biologist prepares a 1.00-kgsample to simulate the ion concentrations in seawater. She mixes 26.5 g of NaCl, 2.40 g of MgCl₂, 3.35 g of MgSO₄, 1.20 g of CaCl₂, 1.05 g of KCl, 0.315 g of NaHCO₃, and 0.098 g of NaBr in distilled water. (a) If the density of the solution is 1.025 g/cm³,what is the molarity of each ion? (b) What is the total molarity of alkali metal ions? (c) What is the total molarity of alkaline earthmetal ions? (d) What is the total molarity of anions?
