A student is working with a 4.95 L sample of carbon dioxide at 22.8°C and 0.956 atm. The student compresses the gas to 1.75 L and increases the temperature of the gas to 65.3°C. What will the resulting pressure of the CO 2 gas be after the student made these changes?

I got 3.07 atm but apparently that's wrong? I used the combined gas law. Is this a possible rounding issue?
