Chapter 1, Problem 1.14A
APPLY 1.14 A sodium chloride solution was prepared in the fol- lowing manner:
• A 25.0 mL volumetric flask (Figure 1.8) was placed on an ana- lytical balance and found to have a mass Of 35.6783 g.
• Sodium chloride was added to flask and the mass of the solid + flask was 36.2365 g.
• The flask was filled to the mark with water and mixed well.
Calculate the concentration Of the sodium chloride solution in units of g/mL and give the answer in scientific notation with the correct number Of significant figures.

aw the major substitution products you would expect for the reaction shown below. If substitution would not occur at a significant
rate under these conditions, check the box underneath the drawing area instead.
Be sure you use wedge and dash bonds where necessary, for example to distinguish between major products.
Note for advanced students: you can assume that the reaction mixture is heated mildly, somewhat above room temperature, but
strong heat or reflux is not used.
