A 90.0 L stainless steel container was charged with 4.00 atm of hydrogen gas and 5.00 atm of oxygen gas. A spark ignited the mixture, producing water. What is the pressure in the tank at a constant temperature of 25°C?

Unfortunately you did not specify the tank temperature before the ignition. Since you said "a constant temperature of 25°C", or "a constant temperature of 125°C", let us suppose the tank temperature was also at either 25°C or 125°C.
At 25°C, the resulting water has been condensed except the saturated water vapor pressure. Hence, the tank pressure is 3.00atm + water vapor at 25°C.
At 125°C, the resulting water all vaporized. Hence, the tank pressure is 7.00atm.
