3. ### A syringe initially holds a sample of gas with a volume of 285 ml at 355 K and 1.88 atm. To what temperature m?

to solve this problem, you have to use the ideal gas law PV = nRT, with pressure P, volume V, moles n, ideal gas constant 0.0821 R, kelvins T first you have to find the number of moles of the gas (n) 1.88 * 0.285 = n * 0.0821 * 355 n = 0.0184...
