3. A newly discovered gas has a density of 2.39 g/L at 23 °C and 715 mmHg. What is the molecular weight of the gas? 4. Acetylene gas, C₂H₂ can be prepared by the reaction of calcium carbide with water: CaC+ 2 H₂O Ca(OH)₂() + C₂H₂(g) 2 Calculate the volume of C,H, that is collected over water at 23 °C by reaction of 0.1580 g of CaC, if the total pressure of the gas is 726 torr? (The vapor pressure of water is listed on the Data Sheet).
