Our final concept of the gas unit is the Ideal Gas Law. This law enables us to determine pressure, volume, temperature, or moles of a confined gas. You will be able to solve problems to identify gases based on measurements in the lab and molar mass.
- Warm Up 77
A gas sample from a lighter has been collected in an inverted container under water. The following data are collected: gas volume= 65.8 mL, water temperature = 22.0°C, total pressure in container = 772 mmHg, vapor pressure of water at 22.0°C = 19.8 mmHg, initial mass of lighter = 5.345 g, final mass of lighter = 5.313 g.
- Gases confined to a container filled with water will always be a mixture of the gas and a small amount of water vapor. Based on the data, what is the partial pressure of the collected gas?
- Solve for the number of moles of this gas.
- Determine the molar mass of this gas.
