If the absolute pressure of a gas is 550.280 kPa, its gage pressure is

A. 101.325 KPa
B. 277.280 KPa
C. 448.955 KPa
D. 651.605 Kpa

C. 448.955 KPa

To find the gage pressure, we need to subtract the atmospheric pressure from the absolute pressure.

Gage pressure = Absolute pressure - Atmospheric pressure

Since the problem doesn't provide the atmospheric pressure, we'll assume it to be standard atmospheric pressure at sea level, which is approximately 101.325 kPa.

Now we can calculate the gage pressure:

Gage pressure = 550.280 kPa - 101.325 kPa = 448.955 kPa

Therefore, the gage pressure is 448.955 kPa.

The correct answer is C. 448.955 kPa.
