Question

1. How is the pressure of the vaporized liquid determine? olume of the flask determined? 3. How is the temperature of the vapor determined? 4. How is the mass of the vapor determined? Use the following data to answer questions 5 and 6. Mass of dry flask, foil and rubber band Temperature of water bath Mass of dry flask, foil, rubber band, and vapor Volume of 125 mL flask Atmospheric pressure 74.72g 98.7 C 74.921g 0.152L 752 torr 5. How many moles of vapor are present? 6. What is the molar mass of the vapor?

Explanation / Answer

To begin with, how about we survey the perfect gas law, PV = nRT. In this condition, 'P' is the weight in environments, 'V' is the volume in liters, 'n' is the quantity of particles in moles, 'T' is the temperature in Kelvin and 'R' is the perfect gas steady (0.0821 liter climates for each moles Kelvin). Much the same as any condition, on the off chance that we know three of those four factors (other than R, which we definitely know since it is a consistent), we can improve the condition to ascertain the obscure.

Ask all remaining questions separately.
