Using the formula for Charles's Law: 
V1/T1 = V2/T2 
We know V1 = 6.5 L, T1 = 50°C + 273.15 = 323.15 K, and V2 = 6.8 L. 
Solving for T2: 
T2 = (V2/T2) * T1 
T2 = (6.5/6.8) * 323.15 
T2 = 308.11 K 
Converting back to Celsius: 
T2 = 308.11 - 273.15 = 34.96°C 
Rounding to the nearest whole number gives: 
Answer: D) 338 K
