energy is required to overcome these attractive forces since the molecules are relatively small. Therefore‚ the liquid vaporizes easily and quickly at temperatures less than 100°C. While the substance is in the vapor phase‚ you can measure its volume‚ pressure‚ and temperature. You can then use the ideal gas law to calculate the number of moles of the substance. Finally‚ you can use the number of moles of the gas to calculate molar mass. OBJECTIVES In this experiment‚ you will • Evaporate a sample

This statesthat “equal volumes of gases at the same temperature and pressure contain the same number of molecules regardless of their chemical nature and physical properties. Molar volume is the volume (22.4 L) occupied by a mole of a substance at STP. The chemical equation for this lab is magnesium plus hydrochloric acid yields to hydrogen gas plus magnesium chloride. The combined gas law explains the relationship among the pressure‚ temperature‚ and volume of an enclosed gas. Also the combined gas

Their influence begins at an early age and increases through the teenage years. It is natural‚ healthy and important for children to have and rely on friends as they grow and mature. Peers can be positive and supportive. They can help each other develop new skills‚ or stimulate interest in books‚ music or extracurricular activities. However‚ peers can also have a negative

dram vial inside the Erlenmeyer flask when the ending volume of N2 gas was recorded. The experimenter shaking and swirling the flask stopped prematurely believing that the reaction was complete. Since all the gas bubbles weren’t released‚ the gas pressure wasn’t completely accurate. With excess gas still remaining in the Erlenmeyer flask‚ the meniscus level was higher on the measuring tube than it should have been. Thus‚ the recorded value for the volume of N2 gas collected was less than it was actually
