- Concentrations and volumes are NOT the same thing. Concentrations are in units of mass/volume (i.e., g/l or mg/ml). Volumes are in units of only volume (i.e., 1. ml). 4. a. If you mixed 265 g of sugar with water to get a final volume of 725 ml. what is the concentration of this solution in g/l? Show your work. If you took 1 ml of this solution, what would the concentration be? Explain your reasoning. you prepare a stock solution (highly concentrated) of sugar in water whose concentration is 500 g/l. you need to make a new solution that is half (1/2) as concentrated and has a final volume of 100 ml. Describe how you would make this dilution. Step one: Your new solution has a concentration of_. Step two: To make 100 ml of this new solution, you will need to add_of concentrated stock solution plus_of water. Now make a second solution that is one-tenth (1/10) as concentrated as the initial stock solution and has a final volume of 100 ml. Describe how you would make this dilution.…In an experiment, identical heat lamps are arranged to shine on two identical containers, one containing water and the other containing, methanol, a nonpolar compound.
