Calculate the osmotic pressure at 25°C of an aqueous solution of 1.00 g/L of a protein having molar mass=2.50×104 g/mol.
Use the initial volume of acetic acid, the volume of NaOH required to reach the equivalence point and the value of the molarity of NaOH that you obtained when you standardized this solution against KHP in the strong-acid/strong-base experiment to ..
What is the pressure in a 65.0L cylinder filled with 0.235 moles of nitrogen gas at a temperature of 105K.
What mass of iron is needed in order to supply the energy needed to warm 15.0mL of water (d= 1.00 g/cm3) from 23C to 37C
a flask that can withstand an internal pressure of 2500 torr, but no more, is filled with a gas at 21.O C and 780 torr and heated. At what temperature will it burst?
A cylinder with a moveable piston contains 0.84 mol of gas and has a volume of 328 mL. What will its volume be if an additional 0.27 mol of gas is added to the cylinder? (Assume constant temperature and pressure.)
Toluene is a liquid compound similar to benzene. Calculate the mole fraction of Toluene in a solution that contains 112 g Toluene and 221 g Benzene.
Explain why Markovnikov's rule is needed to predict the products of hydration and hydrohalogenation, but is not needed to predict the products
Suppose scheme one involves the reaction of the Grignard reagent containing more carbon atoms with the carbonyl compound containing less carbon atoms and scheme two involves the reaction of the Grignard reagent containing less carbon atoms with th..
2500 kg/hr of a mixture containing equal parts by mass of benzene and toluene are distilled. The flow rate of the overhead product stream is 988 kg/hr , and the bottom stream contains 17.03 wt% benzene.
a sample of nitrogen gas occupies 1.55 L at 27.0 C and 1.00 atm pressure. What will the volume be -100 C and the same pressure?
Compute A current is drawn from the cell until 1.20 grams of Ag have been deposited at the Ag electrode. Determine the value of E for the cell at that stage of operation.
