A student prepared a stock solution of the assigned compound by weighing 2.345 grams of Cu(NO3)2. 6H20 and diluting it with water to a final volume of 25.00mL.
From this stock solution, the student then took 2.00mL and diluted it to a final volume of 10.00mL with water. What is the final concentration of this diluted solution?
Bomb Calorimeter, gross heat of combustion, In the following experiment 1.1651g of benzoic acid (6318 cal/gm) produced a net corrected temperature rise of 3.047C, also 8 cm (2.3 cal/cm) of fuse wire were consumed in the firing.
An enzyme-catalyzed reaction produces a product that has a maximum absorbance at 412 nm. The extinction coefficient is 4000 M^-1 cm^-1. A 10-to-1 dilution of the enzyme is made and 20 microliter of the dilution are put into a cuvette with 80 micro..
