I cant remember how to find the partial pressure of o2 when the container has .76 mol of N2, .18 mol of O2, .031 MOl of He, and .026 mol of H2 at 744mmHg.
How can i find the pressure of oxygen if it's in a mixture of .40 moles of oxygen and .20 moles of nitrogen at 1.2 atm pressure

If C 6 H 12 O 6 yields C 2 H 5 OH+CO 2 then balance this equation and determine what the percent yield for the reaction is if 575.0 grams of C 6 H 12 O 6 glucose yields 126.4mL of C 2 H 5 OH ethanol?
The lethal inhalation dose of sarin for a 200lb person has been determined to be 0.0015 mg. Determine the LD50 of sarin that researchers used to calculate this lethal inhalation dose.
Predicting the Polarizability of a Molecule. Consider the following set of data for polarizability. From what I have learned, the simplest model for predicting the polarizability of a molecule is to assume that polarizability scales with the type.
