calculate the final concentration of the solution in each of the following: a)water added to 10.0 mL of a 3.50 M KNO3 solution gives a volume of .250 L. b)a 5.00-mL sample of a 18.0 M sucrose solution is diluted with water to 100. mL. c)water is added to .250 L of a 12.0 M KBr solution to give a volume of 1.00 L.
Consider the following reaction, equlibrium concentrations, and equilibrium constant at a particular temperature. Determine the equilibrium concentration of SO3(g)
What would be the pressure of the gas, in kPa, if it were transferred to a container at 24 degrees Celcius whose volume is 55.0 L.
Determine q for the acid-base reaction, assuming that the liquids have densities of 1.00 g/mL and the same heat capacities as pure water.
The amount of carbon dioxide in a gaseous mixture of CO2 and CO can be determined by passing the gas into an aqueous solution that contains an excess of Ba(OH)2
From this fact, we can deduce that a column of air one square inch in cross-section, measured from sea level to the top of the atmosphere, would weigh approximately 14.7 lb. Given that air has an average molar mass of 28.97 g, calculate the number..
