The answer is 173 psig

Explanation:

R404A is a mixture consisting of R-125, R-143A and R-134a. It is the substitute for R-502 for the refrigeration sector in installations for low and medium temperatures. It is characterized by its chemical stability. Its application is the new installations for low and medium temperatures. According to the pressure-temperature table for this gas that can be consulted on the Internet, at a temperature of 80°F, the pressure at which this gas is located is 173 psig.
