Determine the melting point of an aqueous solution made by adding 186 mg of saccharin (C7H5O3NS) to 1.00mL of water (density = 1.00g/mL, Kf = 1.86Celcius/m).
if the Hindenburg held 2.0x10^5 m^3 of hydrogen gas at 23 degrees Celcius and 1.0 atm, what mass of hydrogen in grams was present?
A 31 L tank contains a gas under a pressure of 617 atm. What volume would the gas occupy at the same temperature at 900 torr of pressure? Answer in units of L.
A 26.0-g sample of ice at -11.0°C is mixed with 123.0 g of water at 90.0°C. Calculate the final temperature of the mixture assuming no heat loss to the surroundings.
A system comprised of 2.900×10^1 g of Ne(g) cools from 170.0°C to 45.0°C at a constant pressure of 5.5 atm. The molar heat capacity at constant pressure for Ne(g) is 20.80 J K?1 mol?1. calculate q,w,delta E, ANDdelta H

What is the freezing point of a 0.19m solution of glucose, C6H12O6, in water? Kf for water is 1.858 C/m
When placed in a graduated cylinder that initially contains 24.00 mL of water, the water level rises to 28.55 mL. What is the density of the unknown material?
assume you completely hydrolyze a sample of the peptide phe-val-lys-ser using the appropriate protease in a phosphate
A piece of galena has a volume of 5.4 cm3. If the density of galena is 7.5 g/cm3, what is the mass (in kg) of that piece of galena?
derive the irreducible representations for the normal vibrations of XeF4 and determine which are IR active, which are Raman active
What is the concentration of free Ni2+ ions in a saturated Ni(OH)2 solution if the pH is buffered to remain at 8.4? The Ksp of Ni(OH)2 is 6.0 x 10^-16.
Hardness in groundwater is due to the presence of metal ions, primarily Mg2 and Ca2 . Hardness is generally reported as ppm CaCO3 or mmol/L Ca2 . To measure water hardness, a sample of groundwater is titrated with EDTA,
