Given the following data generated from this experiment, use theideal Gas Equation to calculate the value of R in L atm/mol K.

DATA

Mass of oxygen evolved= 0.194g

Weight of water displaced by the oxygen generated = 150.823g

Density of Water at 20.3 degrees celsius = 0.99816g/mol

Barometric Pressure = 753.9torr

Temperature of Water = 20.3 degrees celsius

Vapor pressurestaken from the CRC Handbook of Physics and Chemistry

Vaporpressure of water at 20.2 degrees celsius= 17.753 mm Hg

Vaporpressure of water at 20.4 degrees celsius= 17.974 mm Hg

(Hint: since 20.3 celsius is halfway between 20.2 celsius and20.4 celsius, so will the vapor pressure of water at 20.3celsius)

How many grams of water can be cooled from 25 degree celcius to 0 degrees celcius by 180 grams of ice taken from a freezer at -17 degreees celcius? Assume that the final mixture only contains only liquid water at 0 degrees celcius. Assume that no heat is lost to the container or the surroundings.

A reaction of .028g of magnesium with excess hydrochloric acid generated 31.0mL of hydrogen gas. The gas was collected by water displacement in a 22 degrees Celcius water bath. The barometeric pressure in the lab that day was 746mm Hg.

1. Use Dalton's law and the vapor pressure of water at 22 degrees celcius to calculate the partial pressure of hydrogen gas in the gas collecting tube.

2. Use the combined gas law to calculate the "corrected" volume of hydrogen at STP.
