Answer:
Therefore, internal diameter of the glass tube = 1.708 cm
Explanation:
Volume of ethanol = volume of glass tube
volume of ethanol = mass of ethanol/ density of ethanol
volume of ethanol = 45.23 g/ 0.789g/ml
volume of ethanol = 57.326 ml
Therefore volume of glass tube = 57.326 ml
1 ml = 1 cm³
Volume of glass tube in cm³ = 57.326 cm³
Volume of a cylinder = πd²h/4
where h = height of cylinder; d = internal diameter of cylinder
d = √(volume * 4/πh)
d = √(4 * 57.326 cm³ / 3.142 * 25)
d = 1.708 cm
Therefore, internal diameter of the glass tube = 1.708 cm
