    distinguished French chemist‚ created a relatively simple method for determining the molecular mass of a volatile substance. In this experiment we will use a modified version of his technique to determine the molecular mass of an unknown volatile liquid. The density of a gas is given by the ideal-gas equation as‚ Dgas = m PM = V RT where M is the molecular mass of the gas. Solving for molecular mass‚ we obtain: € M= mRT PV Thus‚ the molecular mass of a gas can be determined by measuring the

    heavier‚ it will sink. The force of buoyancy is important in many different areas‚ and especially in the making of ships. The surface area that is touching the water of the ship is very large‚ due to the shape of the hull‚ and that‚ beside the density of the ship‚ is what keeps the ship floating. An important example of how surface area affects buoyancy is when people float in the water. Everyone knows that it is much easier to stay afloat when we are lying on our backs than when we are in a standing
