What is the molarity of a solution made by dissolving 15.1 g of NaCl in enough w

Question

What is the molarity of a solution made by dissolving 15.1 g of NaCl in enough water to make 327.0 ml of solution? Report your answer to three places past the decimal point. What is the molarity of a solution made by dissolving 83.8 g of Mg(NO3)2 in enough water to make 470.0 mL of solution? Report your answer to three places past the decimal point. Check all of the following statements that are true: The free energy change for any spontaneous process is always positive The entropy change of the universe for any spontaneous process is always positive The equilibrium constant is always greater than one for an extensive reaction The value of q is always equal to the value of w for a reversible reaction The equilibrium constant is always equal to one for any system at equilibrium None of these statements are true The energy change of the universe for any spontaneous process is always positive Compare the reaction energy diagrams for the three gas phase reactions shown below. Notice that in all three reaction diagrams, the reactant side (which is related to the A-A bond energy) is at the same energy. Assume that orientation factors are all comparable and that entropy is not important in the following. Specify a reaction with its number (1, 2, or 3). The forward reaction with the largest rate constant is 2 The reaction with largest equilibrium constant is The reaction whose equilibrium constant increases the most with an increase in temperature is The strongest bond is the Select bond. The weakest bond is the Select bond.
