There are a ton of things you can do in the short term to supercharge your savings that you might not be able to do forever.įor example, it’s pretty easy to find 5 or 10 things around the house right now that you can sell on Craigslist to generate some extra cash.
This isn’t the “save $12,000 in a year” challenge for a reason. The goal of this money saving challenge is to save $1,000 in 30 days.

It is essential that you follow the graphing instructions given in the Appendix at the back of the lab manual for making your graph. To calculate the volume after each addition, subtract the initial reading of the buret before any water was dispensed from the current buret reading for a particular sample. To calculate the mass after each addition, subtract the mass of the empty beaker from the current mass (with current amount of water present). Remember that we for each set of data you recorded in Part C on, we want the total cumulative mass and volume after each addition of water (not just the incremental amount since the previous edition. We don't really care what the beaker you used weighs, and we don't care to what level you filled the buret before you started taking water samples from it: we just need the mass of each water sample and its volume. Corrected Mass and Volume After Each Addition of Water

The densities for the three trials (calculated as shown for Trial 1 above) and the average density are given below:ġ. Remember that all three trials should be used (not just Trials 1 and 2). For the mass and volume for Trial 1, calculate the density of the liquid sample, then click here to check your answer. Since the mass is known to 4 significant figures, but the volume is only known to 3 significant figures, the calculated density should only be expressed to 3 significant figures. The density of a liquid sample is the mass of the sample divided by its volume. This is just the difference in mass between the empty beaker and the beaker with the liquid in it! For Trial 1 in the table above, calculate the mass of the liquid sample, then click here to check your result. The volume for Trial 1 (see table above) is 21.6 mL. You measured the volume directly with the graduated cylinder. Remember that you have to average the densities determined in all three trials (not just two).įor the data in the table above, the three individual densities as calculated from the data in the table (in the same manner as illustrated above for Trial 1) are as follows Pay close attention to significant figures! 4. For the solid sample in Trial 1, calculate the density, then click here to check your answer. The density of a sample represents the mass of the sample divided by the volume of the sample. Density of Solid Sample - calculation Trial 1
Based on the data in the table above, calculate the mass of the solid sample for Trial 1, and then click here to check your answer. The mass of the solid sample is just the difference between the mass of the empty beaker and the mass of the beaker with the solid. Mass of solid sample - calculation Trial 1 Calculate the volume of the solid, then click here to check your answer. Since the solid did not react with or dissolve in the water, the volume of the solid in mL is represented by just the change in water levels.
The solid caused the water level for Trial 1 to rise from 25.2 to 30.7 mL. Volume of solid sample - calculation Trial 1
