Question

Describe how you would prepare 250.0 ml of
a.500 m solution of nacl by using apparatus found in a chemistry lab.

Answer 1

Answer:

mols NaCl needed = M x L = 0.500 x 0.250 = about 0.125

grams NaCl = mols needed x molar mass = aboaut 0.125 x 58 (you need to use a better number than this estimate) = about 7.3 g.

Therefore, place 7.3 g NaCl in a 500 mL volumetric flask, add some water, swirl until all of the NaCl is dissolved, then add distilled water to the mark.
