Calculate the vapor pressure of a solution made by dissolving 109 grams of glucose (molar mass= 180.2 g/mol) in 920.0 ml of water at 25°C. The vapor pressure of pure water at 25°C is 23.76 mm Hg. Assume the density of water is 1.00 g/ml.
How is acetyl chloride produced? If 915 gallons is produced and shipped, will DOT require the carrier to display the flammable placard? Explain your answer.
What is the molarity of a solution made by dissolving 74.8 g of strontium perchlorate in sufficient water
Mixture also contains He (helium gas). determine the partial pressure of the He gas?
Find the normal boiling point of a saturated solution of LiF at 100C, assuming it undergoes complete dissociation. The solubility of LiF is 230 mg/100 g of water at 100C
What volume and mass of steam at 100.°C and 1.00 atm would, during condensation, release the same amount of heat as 100. cm3 of liquid water during freezing.
What is the change in enthalpy when 18.4 g of steam at 100?C is converted to liquid water at the same temperature and pressure? The heat of vaporization of water is 40.7 kJ/mole. Answer in units of kJ.
When 9 mL of a solution containing 2.5 M AlBr3 is diluted to 30 mL, a dilute solution is formed. What is the Br- concentration in 15 mL of the dilute solution?
What mass of this substance must evaporate in order to freeze 230 of water initially at 24? (The heat of fusion of water is 334 the specific heat of water is 4.18 .)
The first-order decomposition of phosphene to phosphorus and hydrogen 4PH3(g) → P4(g) + 6H2(g)
calculate the expected change in temperature for 4.5 g of NH4NO3 dissolved in 100.0 mL of H20. Assume that the calorimeter absorbs no heat. (ie. Ccal=0)
The mass of an Argon atom is more than that of a Helium atom. Does that mean that because of Argon has larger mass, it exerts a higher pressure on the walls of container than Helium at the same volume, molar density and temperature? Give explanati..
