A gas occupies 2.00 L at 298 K and 2.10 atm. The volume of this gas at STP is ________.

Question

Quizplus · Accepted Answer

The volume of the gas at STP can be found using the combined gas law: $V_1/T_1P_1 = V_2/T_2P_2$. STP conditions are 273.15 K and 1 atm. Rearranging for $V_2$ gives $V_2 = V_1 \times (T_2/T_1) \times (P_1/P_2)$. Plugging in the values: $V_2 = 2.00 \, \text{L} \times (273.15/298) \times (2.10/1)$, which calculates to approximately 3.84 L.
