    Chemistry vapor pressure questions?

    Naphthalene C10H8 is the substance present in some moth balls. Its vapor pressure at 25C is 0.300mmHg. How many milligrams of naphthalene will sublime into an evacuated 1.000L flask? If 0.700mg of naphthalene is used, what will the final pressure be? What physical states(s) of naphthalene is...

    Confirmation to chemistry question?

    Mc = 1x10-2 = .01M Vc = .5 mL Md = Vd = 100 ml does this meen that Md is equal .0005M???? I am confused by the Molarity and the mL differences in the equation

    Chemistry help please help?

    I obtained a calorimeter and added 10mLs of 6.00M sulfuric acid. I obtained a burette and added 50mLs of 6.00M sodium hydroxide. I collected the pH meter and titration data (This lab was done on the computer). I Started the titration by adding NaOH and watched the temperature. I continued the...

    Can someone give me a walk through of this Chemistry problem?

    A mixture of nitrogen and neon gases contains equal moles of each gas and has a total mass of 10.0g. What is the density of this gas mixture at 500K and 15.00atm? Assume ideal gas behavior.The answer was given( 8.81g/l) but can someone give me a walk through on how to find that solution...

    Can someone give me a walk through of this Chemistry problem!?

    Describe how to prepare a .00500M HCL solution from a bulk solution of 2.0M HCL. The equipment available to you is a 1mL, 5mL, 10,mL, 20mL, and 25mL pipettes; 25mL, 50mL,100mL, and 250mL volumetric flasks. Pipette and volumetric volumes may not be additive. (In other words, if you need 2mLs, you...

    Can someone please take a look at this enthalpy chemistry problem real quick?

    Colorless nitric oxide, NO, combines with oxygen to form nitrogen dioxide, NO2, a brown gas. 2NO(g)+O2(g)-->2NO2(g); Delta H =-114kJ What is the enthalpy change per gram of nitric oxide? Since Delta H =-114kJ per 1 mol wouldnt the enthalpy change per gram I would think the answer would be half...
