paragraph styles 3 a student uses a stoppered 250 ml volumetric flask to determine the density of a liquid the mass of the empty flask and stopper was 251841 g the mass of the stoppered hask 93117

You calibrate a 25-mL volumetric flask by filling to the mark with distilled water, equilibrated at 22^∘ C. The dry stoppered flask weighs 27.278 g and the filled flask and stopper is 52.127 g . The balance uses stainless steel weights. What is the volume of the flask? What is it at the standard 20^∘ C. Also insert the weight in air at 22^∘ C into Table 2.4 (available on the textbook website). and compare the values obtained. | Numerade

SOLVED: An absorbance calibration curve for Na was fitted to the equation A = 1.23[Na, ppm]. In the original solution, a 5.00 mL aliquot of an unknown Na solution was diluted to 50.0 mL in a volumetric flask; the absorbance from this sample was measured to be 0.193. To a second 50.0 mL volumetric flask, a 5.00 mL aliquot of the unknown Na sample and a 0.50 mL aliquot of 10.00 ppm Na solution were added and diluted to the mark; the absorbance from this sample was measured to be 0.280.
