Answer: 2.576 kPa
Explanation:
Since the volume does not change, the formula: P/T = P/T can be used.
However, all temperatures must be in kelvin, so to convert the -62 Celsius add 273 and get: 211 K.
Now, plug in to the formula: 6.58 / 539 = P / 211 → Cross multiply and then divide to get: P = 2.576 kPa :)
