Question
Data: Mass of empty flask 44.286 gFlask plus water 54.225 g Triet is using a 10 mL volumetric pipet. He transfers 10 mL ofwater into a flask, then weighs the flask. (A volumetric pipet isaccurate to two places after the decimal, so the volume is10.00 mL with correct significant figures. Use 0.9982 g/mL as thedensity of water at room temperature.) Data: Mass of empty flask 44.286 g Flask plus water 54.225 g a) Using Triet's experimental values for the mass of the water,calculate the volume of water delivered to theflask. b) Calculate the relative range for Triet's experiment. (How do youcalculate relative range? Read the first page of your handout forthis lab, or page 190 of your lab manual.)
Explanation / Answer
a) Mass of water = 54.225 - 44.286 = 9.939g Density = mass/volume 0.9982 = 9.939/volume Volume of water = 9.96 mL b) it depends on your lab manual. I cannot help without your labmanual. Hope this helps!
