What is the scientific method answers to the freezing point of water
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 7 pieces of 0.97 cm diameter and 1.14 cm height cylindrical beads is determined to be 1.63 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 46.86 g. Upon further inspection, it was found that manufacturing defects caused the measured porosity of the beads to be at 32%. Assuming that the solution was able to fully fill the empty spaces inside the beads, calculate the density of the salt solution.

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 13 pieces of 0.6 cm diameter and 0.67
cm height cylindrical beads is determined to be 1.53
g/mL. These beads were then placed in a flask and was
filled to the 42 mL mark with a salt solution. The total
weight measured of the beads and the salt solution
was 51.68 g. Upon further inspection, it was found that
manufacturing defects caused the measured porosity
of the beads to be at 21%. Assuming that the solution
was able to fully fill the empty spaces inside the beads,
calculate the density of the salt solution.
