A 2.75-L container filled with CO₂ gas at 25°C and 225 kPa pressure springs a leak.When the container is re-sealed,the pressure is 185 kPa and the temperature is 10°C.How many moles of gas were lost? A)0.0335 mol B)0.728 mol C)0.882 mol D)3.39 mol

Using the ideal gas law, calculate the initial and final moles of gas, then find the difference. Initial moles: n1 = (225 kPa * 2.75 L) / (8.314 * 298 K) = 0.251 mol. Final moles: n2 = (185 kPa * 2.75 L) / (8.314 * 283 K) = 0.2175 mol. Moles lost: 0.251 - 0.2175 = 0.0335 mol.
