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. Show your solutions in the next item Round your answer to 2 decimal places. Add your answer

A chemistry student must write down in her lab notebook the concentration of a solution of sodium thiosulfate. The concentration of a solution equals the mass of what's dissolved divided by the total volume of the solution. Here's how the student prepared the solution: • The label on the graduated cylinder says: empty weight: 8.25 g • She put some solid sodium thiosulfate into the graduated cylinder and weighed it. With the sodium thiosulfate added, the cylinder weighed 18.845 g. • She added water to the graduated cylinder and dissolved the sodium thiosulfate completely. Then she read the total volume of the solution from the markings on the graduated cylinder. The total volume of the solution was 177.59 mL. What concentration should the student write down in her lab notebook? Be sure your answer has the correct number of significant digits.
A fictional cubed-shaped bacterium, Bacterius cubis, occupies a volume of 2.8 femtoliters. This particular type of bacteria is known to communicate with its own species by secreting a small molecule called bactoX (MW = 122.4 g/mol). A. Each bacterium contains 8850 bactoX molecules that can be secreted. How many moles of bactoX are present in a 1.2 µL sample volume that contains 3.234 x 10° bacterial cells? 4.75 x10-18 moles: mol Incorrect B. Calculate the molarity (mol/L) of bactoX in the 1.2 µL sample volume if all of the bacteria were to simultaneously secrete all of the bactoX molecules contained within their cell bodies into the vial. 3.96 x10-12 concentration: M Incorrect

A 15000 L tailings pond at a mine site was analyzed for cadmium contamination. First, a 25.0 mL sample of water was removed from the pond. Then the solution was evaporated to dryness, and 56.1 mg of cadmium was recovered (the identity of the metal was confirmed through other methods). Assuming the water is homogeneously distributed throughout the pond, what is the concentration of cadmium in the tailings pond?
