Kiki, Karl’s twin sister, did a lab just like our butane lab. But she did not have butane  as her gas. Use the Ideal Gas law to help Kiki determine the molecular mass of the  gas from the following data. A sample of a gas is collected by water displacement.  ➢ The mass of the gas cylinder before releasing the gas is 25.00g. ➢ The mass of the gas cylinder after releasing the gas is 21.08g.  ➢ The volume of the gas is 3.35 L.  ➢ The barometric pressure is 740.2mmHg.  ➢ The room temperature is 28.0ºC and

Part 1: Gas Laws The physical properties of gases can be explained using four variables; volume (V), pressure (P), temperature (T), and amount in number of moles (n). Four simple laws are used to explain the behavior of gaseous species. Complete the table below to summarize the four gas laws. Name of the gas Properties that Properties that Gas law equation Gas law explanation law stay constant are changing n and T P:V1 = P:V2 Charles's law T and V are directly proportional. (as T increases V also increases) Pand T P1 P2 T1 T2 Avogadro's law V and n

4. Suppose a gas mixture used for anesthesia contains 4.00 mol oxygen (O₂) and 6.00 mol nitrous oxide (N₂O). The total pressure of the mixture is 2.00 atm. a. A mole fraction is defined as the moles of a specific component divided by the total number of moles present. What is the mole fraction of N₂O in this mixture? b. What is the partial pressure in atm of O₂ in this mixture? c. What is the partial pressure in atm of N₂O in this mixture?   5. A gas is formed in the reaction shown below. The gas laws can help determine the volume of gas produced. Zn(s) + 2 HCl(aq) → ZnCl₂ + H₂(g) a. In the last part, you determined that you started with 2.001 moles of Zn. How many moles of H₂ gas will be formed in this reaction? b. At STP, what volume in L of H₂ will be produced? Remember the gas constant, R, is 0.08206 L･atm/mol･K.   6. When the ideas from Boyle’s Law, Charles’ Law and Gay-Lussac’s Law are combined, you get the combined gas law. This law combines the effects of pressure, temperature…
