For many purposes we can treat propane $(C_3{H}_8)$ as an ideal gas at temperatures above its boiling point of $-42.C.$

Suppose the temperature of a sample of propane gas is lowered from $16\mathrm{.}0C$ to $-15\mathrm{.}0C,$ and at the same time the pressure is changed. If the initial pressure was $0\mathrm{.}71$kPa and the volume decreased by $30\mathrm{.}0\%,$ what is the final pressure? Round your answer to $2$ significant digits.
