Experiment 1 Pre-lab Questions 1. A 200.00 mL volumetric flask is placed on an electronic balance, the display is set to zero and the flask is filled to the mark with distilled water at 25°C·The displayed mass for the water in this flask is 1929.2094 g. The density of the surrounding air is 1.20 X 103 g/cm3 and the balance has been calibrated using a 8.00 g/cm3 reference weight. What is the true volume of the flask at 25°C? (Refer to your lab handout for the calculation and the buoyancy correction factor)

Explanation / Answer

mass = volume *density

volume = mass/density

             = 1929.2094/8 = 241.15ml
