Answer to Question #81453 in General Chemistry for Parker Harris
Question #81453
A empty flask has a mass of 79.31 grams. A 25.0 mL sample of an unknown liquid was pipetted into the flask and gave a total mass (flask plus liquid) of 97.010 grams. The density of the unknown liquid was
Expert's answer
m(liquid) = total mass - mass of a empty flask = 97.010g - 79.31g = 17.7 g
density of the unknown liquid = m/V = 17.7g/25ml = 0.708 g/ml
density of the unknown liquid = m/V = 17.7g/25ml = 0.708 g/ml
