of a 0.9% solution of sodium chloride
(NaCI), we would weigh 0.9 g of NaCl (solute) and dissolve
it in some distilled wate (solvent). When the salt is totally
dissolved, enough distilled water is added to make a final volume
of 100 mL. When measuring solutions in a cylinder, pipette,
or volumetric flask, be sure to hold the calibrated glassware at
eye level to read the bottom line of the curved surface of the
liquid (the meniscus). Volumetric glassware should be used fo
solution preparation; calibrated Erlenmeyer flasks or beakers
too inaccurate. The size of calibrated glassware chosen shoul
equal to or just slightly larger than the volume desired so tha
error of measurement will be minimal.
