Answer to Question #126949 in Physical Chemistry for Asad Amin

Question

1) Describe how you would prepare 1 L of a 1 M solution of sodium chloride. The gram formula weight of sodium chloride is 58.44 g/mol.
2) Describe how you would prepare 1 L of a 2 M solution of acetic acid. The gram formula weight of acetic acid is 60.05 g/mol, and its density is 1.049 g/mL.
3) Describe how you would prepare 100 g of a solution that is 0.5% phenolphthalein by mass.

Answer 1

1.)   1 L of a 1 M solution of sodium chloride = 1Moles of NaCl Present in 1 liter of Solution .

2 . )  1 L of a 2 M solution of acetic acid. = 1liter Solution Contain 2 moles Of Solute ( CH₃COOH).

3 . )  100 g of a solution that is 0.5% phenolphthalein by mass. = 100g Solution Contain 0.5 g of phenolphthalein .
