Question
Porosity is a measure of the void or empty spaces
in a material and is a fraction of the volume of
voids over the total volume. The density of the solid
material used to create 11 pieces of 1.39 cm
diameter and 0.65 cm height cylindrical beads is
determined to be 2.24 g/mL. These beads were
then placed in a flask and was filled to the 40 mL
mark with a salt solution. The total weight
measured of the beads and the salt solution was
51.96 g. Upon further inspection, it was found that
manufacturing defects caused the measured
porosity of the beads to be at 26%. Assuming that
the solution was able to fully fill the empty spaces
inside the beads, calculate the density of the salt
solution.
Expert Answer
Step1
a)
Transcribed Image Text:It is given that the mass of the beads and the salt
solution is 51.96 g.
Step7
g)
Therefore, the mass of the salt solution is
51. 96 – Mass of bead=51.96 – 17. 985
=33. 975 g
Step8
h)
Now, the density of the salt solution is
Mass

Volume
33.975
40
=0. 85 g/ml
Step9
i)
The density of the salt solution is 0.85 g/ml.
