if the absolute pressure of a gas is 550.280 kpa, it's gage pressure is what?

To find the gauge pressure of a gas when the absolute pressure is known, you can use the formula:

Gauge Pressure = Absolute Pressure - Atmospheric Pressure

However, since the atmospheric pressure is not given in the question, we can assume that the gas is in a closed system where the atmospheric pressure is negligible. In this case, the gauge pressure is equal to the absolute pressure.

Therefore, the gauge pressure of the gas will also be 550.280 kPa.
