Question

A sample of nitrogen gas has a pressure of 745 mm HG at 23 degrees C. What is the pressure when the temperature rises to 146 C?

Answer 1

\[P _{1}V _{1}\div T _{1} = P _{2}V _{2}\div T _{2}\] is the equation.... you need to get Celsius to Kelvin.... so add 273 to get kelvin... so right now the equation with everything plugged in is \[\frac{0.98 }{ 296 } = \frac{ x }{ 419 }\]
cross multiply to get
\[410.62 = 296x\]
divide 410.62 by 296 and you will get
\[x \approx 1.387 atm \]
\[1.387atm \approx 1054.295 mm Hg\]
to get that just multiply 1.387 by 760( the amount of Hg at 1atm )
Hope this helped

Answer 2

That is the equation for the combined gas laws.... If you start with that equation then ignore the constant you should always get the right answer
