2. With the given information: i) State the gas law that can be used and ii) Solve for the unknown. a. If a 425mL of He gas is cooled from 76°C to 22°C, what is the new volume of the gas? Gas Law: Solve for the Unknown: b. The new pressure of a gas when it expands to 1.25L when originally 235mL and 5.34atm. Gas Law: Solve for the Unknown: c. If 23.4grams of Argon is at a volume if1.35L, what volume will the same mass of Cl₂ gas take up given that all other conditions are the same? (hint for this one-compare moles) Gas Law: Solve for the Unknown: d. If 464mL of an ideal gas is at 27°C and 1.05atm, what will be new volume at STP? Gas Law: Solve for the Unknown:
