Very lost, please help with an explanation about which steps to take & formulas to use. Thank you!

1. (Step 1): How many grams of sodium chloride will you weigh out to make a 100 ml solution of 0.5 M sodium chloride (MW=58.5 g/mol)? Show your work. (2 points) 2. (Step 2): Make 100 mLs of 0.0005 M NaCl solution using three 1:10 serial dilutions of the NaCl prepared in Step 1. Answer the following questions and show all of your work. a. Use C.V.-C2.V2 to calculate the volume of solution needed to be taken from each of the dilutions to make the next dilution. (1 point)
