A 5.00 L sample of hydrogen gas held at 22.0°C has a pressure of 4.20 atm. What will the pressure of the gas be if the volume of the sample
expands to 10.0 L and the temperature increases to 33.6°C?

The kw for water at 0 °c is 0.12× 10–14 m2. calculate the ph of a neutral aqueous solution at 0 °c.
