The student calculates the density of the pipet from the mass and volume data. Determination of the mass of the pipet 1 pt 2. The student uses displacement of water to find the volume of the pipet but fails to subtract the internal volume. The student uses the likely approach procedure to find volume. Calculation of density for the pipet.
Students can solve the problem without destroying the Beral-type pipets.
However, students may decide to cut up the pipet in order to measure the volume of the plastic. It is also possible to collapse the pipet by heating and then to measure the volume of the plastic by water displacement. Any size Beral-type pipet will be suitable, but match the size of the pipets used to the size of the cylinders provided. 25-mL cylinders may be needed if large size pipets are used.
