Final answer:
To find the new volume of the gas, you can use the combined gas law. The new volume of the gas is approximately -67.22 L.
Step-by-step explanation:
To find the new volume of the gas, we can use the combined gas law. According to the combined gas law, the initial volume divided by the initial temperature is equal to the final volume divided by the final temperature. We can rearrange this equation to solve for the final volume:
V1/T1 = V2/T2
Substituting in the values, we have:
605 L/27°C = V2/-3°C
V2 = (605 L/27°C) * (-3°C)
V2 = -67.22 L
Therefore, the new volume of the gas is approximately -67.22 L.
