How do the presence or absence of partial charges at the molecular scale help explain a liquid's ability to dissolve salts? O The presence of partial charges on liquid molecules can attract charged ions and separate ions in solution Partial charges on liquid molecules are different than the charges on ions, so they will not attract one another OThe absence of partial charges on liquid molecules can attract charged ions and separate ions The presence of partial charges on liquid molecules repel the charged ions, causing ions to bind more tightly to each other

3. Calcium chloride (CaCl2) has a formula mass of 110.98 g/mol. A 1.00-g sample of NaCl (FM 58.44) and a 0.500-g sample of CaCl2 are mixed together, dissolved in water, and diluted to a final volume of 100.0 mL. Then 20.00 mL of this solution is pipetted into a separate flask and diluted to a final volume of 50.00 mL. What is the molarity of chloride ion in this new solution?
