1. (2 pts) Indicate whether each statement below is True or False (T or F). If the answer is false, describe how you would change the statement to make it true.

1. __________ You lose a little bit of the NaCl from the weigh boat prior to adding it to the volumetric flask, your solution will end up being higher in NaCl concentration than you expect.

b. __________ The volumetric flask had several drops of deionized water in it before the NaCl was added. Deionized water was then added to the mark in the volumetric flask. The fact that water was in the flask prior to the salt being added results in a lower concentration of the salt solution.

2. (2 pts) What is the concentration (in moles/liter) of a sodium chloride solution in which 4.000 g was transferred to a 250.0 mL volumetric flask and diluted to the mark with deionized water? Show work and express your answer with the correct number of significant figures.
