A solution has a volume of 2.0 L and contains 36.0 g of glucose (C6H12O6). If the molar mass of glucose is 180 g/mol, what is the molarity of the solution.
A gas mixture contains helium and oxygen at respective partial pressures of 255 torr and 0.450 atm. What is the total pressure in mm Hg of the mixture?
You perform column chromatography on a mixture of reaction products which shows two spots on TLC. However, under the column conditions you chose those two compounds do not separate.
Important information about Finding expressions for the partial molar volumes at T and P, The molar volume (cm^3 mol^-1) of a binary liquid mixture at T and P is given by: V = 120x1 + 70x2 + (15x1 + 8x2)x1x2 (a) Find expressions for the partial mo..
Calculate the slope of the straight line 2. What is the density of the substance 3. Briefly explain why it is more accurate to use the slope of the plot to determine the density than it is to use data from a single determination
Calculate the percent yield of if the reaction produces 169g of C2H5Cl .
Considering the mixture of the two compounds and range of the melting points, the reason recrystallization was difficult was due to a broad melting point range.
Primary alcohols can be oxidized to aldehydes and carboxylic acids. Often it is difficult to stop at the aldehyde oxidation state. One method frequently used to accomplish
