Answer:
0.75 L
Step-by-step explanation:
V1/T1 = V2/T2
V1 = 0.520 L
T1 = 18 C = 291 K (make sure to convert to Kelvin by adding 273 to the Celsius temperature)
V2 = ?
T2 = 422 K
Solve the equation for V2
V2 = V1T2/T1
V2 = (0.520 L)(422 K) / (291 K) = 0.754 L ≈ 0.75 L (since it says to only give two significant figures)
