Glucose makes up about 0.10\% by mass of human blood. Calculate the concentration in ppm. Calculate the molality. What further information would you need to determine the molarity of the solution?
Consider a solution that contains 66.0% R isomer and 34.0% S isomer. If the observed specific rotation of the mixture is -30.0°, what is the specific rotation of the pure R isomer
A gaseous system undergoes a change in temperature and volume. What is the entropy change for a particle in this system if the final number of microstates is 0.617 times that of the initial number of microstates?
Using the Nernst equation, calculate the effect on the cell potential of increasing the Fe2+ ion concentration from 1.0 M to 2.0 M for each of the following reactions. The concentration of the other solution remains at 1.0 M
Nitrogen dioxide reacts with water to produce oxygen and ammonia; 4NO2(g)+6H2O(g)-->7O2(g)+4NH3(g). At a temperature of 415 degrees C
Calculate the number of moles of ions produced when one mole of Co(NH3)4Cl3 is dissolved in water.

In acid based titration, 33.65mL of an 0.148 M M HCL solution were required to neutralize 25.00 mL of a NaOH solution . What is the molarity of the NaOH solution
The kinetic energy of the emitted electrons is measured to be 11.7 eV. What is the first ionization energy of Hg in kJ/mol? kJ/mol (d) Using this figure of ionization energies, determine which of the halogen elements has a first ionization energy ..
Calculate the pressure, in atmospheres, of 3.94 mol CO(g) in a 4.25 L tank at 31 degrees C.
A chemical plant produces an ammonia-rich waste gas that cannot be released as-is into the environment. One method to reduce the ammonia concentration in the waste gas is to bubble the waste gas through a liquid solvent.
estimate the amount of carbon dioxide (in tonnes) that is consumed over a 6-month period by the forest, assuming trees are 50% glucose and 50% water. How much sunlight (in GJ) has the forest absorbed in that period?
