conduct the experiment below:
You will now test the porosity (the space between the particles) of the soil. You'll compare the porosity of the soil with the porosity of sand and pebbles by measuring how much water fits in a glass with the same amount of each material. Note that the sand will be made up of a combination of fine and coarse sand particles. All of the pebbles, on the other hand, will be of roughly equal sizes.
Set three identical glasses on the counter or table. Put the half cup of sand in one glass, the half cup of pebbles in the second glass, and a half cup of your soil sample in the third glass.
Working with one sample at a time, add water to the glass one tablespoon at a time. Water should soak the sample from the bottom up. Count the number of tablespoons of water it takes bring the water level up to the top of the sample. Record the amount in the chart.
Calculate the porosity of each sample using this formula, and record the results in the chart. “Total sample volume” is the amount of soil, sand, or pebbles in the sample. A half cup is equal to 8 tablespoons.
% porosity = (amount of water added to sample ÷ total sample volume) × 100

Calculate: select the worksheet tab. this tab you calculate the analyte concentration. fill in the first set of boxes ("moles h2so4" and "moles naoh") based on the coefficients in the balanced equation. (if there is no coefficient, the value is 1.) record the appropriate volumes in the "ml naoh" and "ml h2so4" boxes. record the concentration of the titrant in the m naoh box. click calculate. what is the concentration listed
