Answer to Question #182094 in General Chemistry for Madison

Question

A container is filled with an ideal gas to a pressure of 11.0 atm at 0oC.

  a. What will be the pressure in the container if it is heated to 45o C?

Answer 1

From the ideal gas equation;

$P1V1\over T1$ $=$ $P2V2\over T2$

$P1=11.0atm$

$T1=(0+273K)$

$V1=22.4L(STP )$

$P2=unknown$

$T2=(273+45)$

$V2=22.4L(STP)$

Applying the formula;

$P2=$ $P1V1T2\over V2T1$

$P2=$ $11.0\times \cancel {22.4}\times 318\over \cancel{22.4}\times 273$ $=12.81atm$

$\therefore P2=12.81atm$
