Chemisty HELP ASAP
In this problem, your answers should be mathematical expressions involving a variable. Consider an ideal gas with an absolute temperature of T1 To what temperature would you need to heat the gas to double its pressure? T2=? I got T2=2P but it is wrong

Chemistry
It is 65.4g/mol

Chemistry
P=.995atm V=.205L n=? R=.0821 Lxatm/molxk) T=298K

Chemistry
n=.0833 mols molar mass=(.0833mols/.528g)=.158g/mol

Chemistry
A 0.528 gram sample of a metal, M, reacts completely with sulfuric acid according to: M+H2SO4 -> MSO4+H2 A volume of 205 mL of hydrogen is collected over water; the water level in the collecting vessel is the same as the outside level. Atmospheric pressure is 756.0 Torr and...

Chemistry Answer?
Is the answer 3.24x10^-3 g/mol?

Chemistry
T1 is 288K but what is T2?
