Sample Lab Report: Molar Volume Of Hydrogen Background: Gasses are a special phase of matter that can be described if one knows the pressure, temperature, and volume of the system filled by the gas. We will employ various techniques of measuring these variables. Since we will be collecting gas over water we will need to use Dalton’s law of partial pressures to assure a proper reading of gas pressure. Purpose: To verify Avagadro’s law – “All gasses will occupy 22.4 Liters volume when one mole is present in the sample and the pressure and temperature are held at STP. Hypothesis: The hydrogen gas collected in this experiment when converted to conditions of STP (O degrees C and 1 atm) will be close to 22.4 L/mol Procedure: 5 mls of 2 M. HCl were poured into the bottom of a 10 ml graduated cylinder. Water was decanted on top of the HCl carefully so not to mix the HCl and added so that the cylinder was completely filled with liquid. A one cm strip of magnesium was affixed to the tapered end of a cork with a hole it it and this cork was placed on top of the graduated cylinder. The cylinder was quickly inverted and the end placed under water
