then calculate x. You can use the spreadsheet program to do this calculation for you and make it quicker. You have now calculated the concentration of the chemical of interest in three of your diluted unknowns. The original solution was diluted to prepare these unknowns, however...

Learn how to calculate the concentration of a solute in grams per liter, and see examples that walk through sample problems step-by-step for you to improve your chemistry knowledge and skills.
a mathematical formula involving the initial concentrations of the two solutions, as well as the volume of the final solution, allows you to work out the final concentration in percent of the volume of the new combined solution.
Sounds pretty trivial to me. The sample in solution is put into a vessel that can handle vacuum, you pump the air out, and as the solvent evaporates, you keep pumping that vapor out, until you've lost "enough" to get the concentration needed for the next step. I recognize you're con...
Molarity is a familiar way to express concentration in chemistry. Take the number of moles, which is obtained from the molar mass, and divide by the number of liters. Normality takes into account reactive equivalents. The normality formula is N = Mn, wer
Brain Chemistry During Alcohol Use Like any other addictive drug, alcoholaffectsthe brain’s chemistry. When a person drinks alcohol, the drug causes their brain to release neurotransmitters responsible for signaling pleasure and reward (among other things). In the brain, alcohol increases the effects...
We get to the office full of high resolve, only to watch the minutes and hours dribble away in unproductive activity. We look over the newspaper, amazed that we never realized before how interesting the shipping news was. We check with coworkers to see how things are going at their end ...
Low solubility in aqueous media will drastically lower the concentration of the drug causing a poor bioavailability. Nanoparticles can provide an alternative medium for these drugs to be solubilized in and carried out through the body to the targeted tissue or organ. The extensively small sizes of ...
Investigate how varying the concentration of borax in the solution affects crystal formation. Prepare solutions with different concentrations of borax (e.g., 100g/L, 200g/L, 300g/L) and observe the resulting crystals to determine if higher concentrations produce larger or more complex crystals. ...
