Problem

A 1.00 mol sample of CO2_2 is confined to a rigid 10.0 L vessel at 250 K. The measured pressure of the gas is 1.70 atm. What is the percent deviation of the measured pressure from the pressure predicted by the ideal gas law, calculated as Preal−PidealPideal×100%\displaystyle\frac{P_{\text{real}}-P_{\text{ideal}}}{P_{\text{ideal}}}\times100\%? (a) +21%+21\% (b) −17%-17\% (c) −21%-21\% (d) +17%+17\%
