A gas sample occupies 3.50 liters of volume at 20.°C.What volume will this gas occupy at 100°C (reported to three significant figures)?

To solve this problem, we can use the combined gas law equation:
(P1V1)/T1 = (P2V2)/T2
where P is pressure, V is volume, and T is temperature. We can assume that the pressure and moles of gas remain constant. We are given V1 = 3.50 L and T1 = 20°C + 273.15 = 293.15 K. We want to find V2 when T2 = 100°C + 273.15 = 373.15 K. Plugging in the numbers, we get:
(P1)(3.50 L)/(293.15 K) = (P2)(V2)/(373.15 K)
Since P1 and P2 are constant, we can cancel them out. Solving for V2, we get:
V2 = (3.50 L)(373.15 K)/(293.15 K) = 4.46 L, which is closest to choice C.
