The solubility of benzoic acid (molar mass = 122 g/mol) in water is 0.0282 M at 298 K. Suppose 2.87 grams of benzoic acid are used to prepare a 168 mL solution.
Calculate the concentration of the solution in units of molarity (M).
Report your answer to 3 decimal places.

Using data from seismic waves, geologists have learned that earth’s interior is made up of several

Why is the bond angle in a water molecule less than the bond angle of methane? a. the central oxygen atom in water has two lone pairs of electrons, whereas the central carbon atom in methane has no lone pairs. b. the central hydrogen atom in water has one lone pair of electrons, whereas the central carbon atom in methane has two lone pairs. c. the central oxygen atom in water has four lone pairs of electrons, whereas the central carbon atom in methane has only one lone pair. d. the central oxygen atom exerts more repulsive force on surrounding atoms than the central carbon atom in methane does. reset next
