Question

POST-LAB QUESTIONS (15 PTS.) 1. (2) Which type of glassware affords the most precise volume measurement, beaker, graduated cylinder or volumetric flask? Volumetric flask Explain: The volumetric flask has been precisely messure for specific volume has one marking only on the flask. The beaker and graduate cylinder, have more. The volumetric flask also has messurment to the hundths A 23.4 mL volume of a pure liquid has a mass of 28.4443 grams at 25.0°C. a. (3) Calculate the density of this liquid at 25.0°C. mass = 28.4443 g volume = 23.4 mL density = 28.4443 g / 23.4 mL = 1.22 g/cm^3 (3 s.f)

A 23.4 mL volume of a pure liquid has a mass of 28.4443 grams at 25.0°C.
a. (3) Calculate the density of this liquid at 25.0°C.
mass = 28.4443 g
volume = 23.4 mL
density = 28.4443 g / 23.4 mL = 1.22
