I am stuck on this last question can someone help me ? A gas has a pressure of 50.0 mm Hg at 247°C. What will be the final temperature, in K, if the pressure changes to 2.53 kPa and the volume does not change?
I have been trying to use the formula (V1)P1) / (n1)(T1) = (V2)P2) / (n2)(T2) but can not get to the answer.

Listen base your answer to the question on the information below. propane is a fuel that is sold in rigid, pressurized cylinders. most of the propane in a cylinder is liquid, with gas in the space above the liquid level. when propane is released from the cylinder, the propane leaves the cylinder as a gas. propane gas is used as a fuel by mixing it with oxygen in the air and igniting the mixture, as represented by the balanced equation below. c3h8(g) + 5o2(g) → 3co2(g) + 4h2o() + 2219.2 kja small amount of methanethiol, which has a distinct odor, is added to the propane to consumers detect a propane leak. in methanethiol, the odor is caused by the thiol functional group (–sh). methanethiol, ch3sh, has a structure that is very similar to the structure of methanol. what is the correct structural formula for a molecule of methanethiol
