Find the molar mass of gas using ideal gas law Mireille Tannous 2019-11-21 | In this experiment we used a volatile liquid which we turned to gas by immersing it in a hot bath or water. This liquid that evaporated to gas was trapped in a flask. The mass was recorded before and after forming the gas in order to know the mass of gas used.A labquest device in which we connected a pressure sensor and temperature sensor was used to determine the pressure at which the experiment was operated and the temperature at which the gas formed. To know the volume of the gas (volume of container occupied) we had to fill the flask completely with water and measure the volume of water (volume of gas to be).Finally when all was set molar mass was calculated using the ideal gas law: Molar mass = m.R.T/P.V

How to differentiate between mixtures Mireille Tannous 2018-02-01 | Suspension is a heterogeneous mixture and it can be directly recognised from other mixtures simply by observing the particles settling out once we stop mixing it. The particles in a suspension are large enough to settle out. Whereas particles in a solution or colloid are not heavy to settle out neither can be filtrated. For this reason we use the Tyndall effect light to see which mixture's particles scatter light. As a result the colloid particles are large enough to scatter light while the solution particles are very small to reflect the light.
