Problem: A 10.0 cm long cylindrical glass tube, sealed at one end, is filled with ethanol. The mass of ethanol needed to fill the tube is found to be 11.88 g . The density of ethanol is 0.789 g/mL.Calculate the inner diameter of the tube in centimeters.

FREE Expert Solution

Calculate the volume of ethanol used:

volume ethanol=11.88 g×1 mL0.789 g

volume ethanol = 15.057 mL

volume ethanol = volume inner space of the tube

1 mL = 1 cm3

volume of inner space = 15.057 cm3


Calculate the inner radius of the tube in centimeters:

V=πr2hVπh=πr2hπhVπh=r2r=Vπhr=15.057 cm32π(10.0 cm)r=1.5057 cm2π
