You have an elastic container that initially had a volume of 3L, holding 13mol of an ideal gas while at 25°C and under 0.75atm. If the temperature increased to 41°C while
the volume was increased to 4L then what would be the resulting pressure in
atmospheres inside of the container? Numerical Answer only, with 2 Significant
figures
