Answer:

To find the pressure of the hydrogen gas, you need to subtract the vapor pressure of water at the given temperature from the total pressure. At 19.0°C, the vapor pressure of water is approximately 17.5 mmHg. So, the pressure of the hydrogen gas would be 770.0 mmHg - 17.5 mmHg = 752.5 mmHg.
