A 25.0 mL sample of gas is enclosed in a gas-tight syringe at 22oC. If the syringe is immersed in an ice bath, what is the new gas volume? I have gathered that; V1=25.0mL T1=22C +273=295K V2=??? T2=273? I need to know if my information is correct.

    Well I'm trying to use the Charles Law. However I am a little confused about what the second temperature will be. It says that the syringe is put in a ice bucket, then I have to find the new volume. I took a guess at 273K.

    I ended up getting 23.1355. (Now I will round) However, I am given options for the answer and this doesn't match any of them. I don't know what I'm missing from the problem.

    @grimsnightmare how does your equation look? What is the general form of Charles' Law?

    sorry the general formula is V1/T1=V2/T2 However I changed it to: V2 = T2*V1/T1

    your rearrangement is correct, I don't know why you'd get an answer different than one of the options, unless there's a mistake in the problem itself. I get 23.15mL as well, so I don't know what to tell you

    I figures out the problem. So if you were to work the problem by the original formula writing like this; 25.0 / 295 it equals 0.0847 You would round this right? My teacher didn't round to .085 so the problem was coming out all wrong.
