What is the percent by mass of NaHCO3 in a solution containing 10 g of NaHCO3 dissolved in 300 mL of H2O
rates of reactions can be determined by monitoring the change in concentration of either reactants or products as a
A patient recieves all her nutrition from fluid given through the vena cava. every 12 hours, 750mL of a solution that is 4%(m/v) amino acids (protein) and 25% (m/v) glucose (carbohydrate) is given along with 500 mL of a 10%t (m/v) lipid (fat)
dissolved in water and completely neutralized by the addition of 43.70 mL of 0.303 M NaOH. Calculate the molar mass of the acid, assuming it to be a monoprotic acid.

In an electrolysis experiment such as the one you will perform, 1.76 x 10^-3 moles of hydrogen gas were collected, and the metal electrode lost 0.1983 g. The equivalent mass of the metal is approximately what?
calculate (Triangle H degree R) for the following reaction- H2S(g) + (3/2)O2(g) ---> SO2(g) + H2O(g)
A 25:75 mixture of acetone:toluene is heated to 70 C at a pressure of 760 mmHg. What is the total vapor pressure of the system? Is the system a liquid below boiling, at boiling, or a gas?
An injection containing 10.0pg 10 5 B was injected into a patient suffering from a brain tumor. The patient was irradiated by a neutron gun at the site of the tumor.
