Question

The vapor pressure of water at 25.5 C is approximately 24.5 mmHg.

the total pressure of gas collected over water is 758.0 mmhg and the temperature is 25.5 Celsius. what is the pressure of hydrogen gas formed in mmhg?

Answer 1

To find the pressure of hydrogen gas formed, subtract the vapor pressure of water from the total pressure of gas collected over water.

Step-by-step explanation:

To find the pressure of hydrogen gas formed, we need to subtract the vapor pressure of water from the total pressure of gas collected over water. In this case, the vapor pressure of water is 24.5 mmHg and the total pressure is 758.0 mmHg. So, the pressure of hydrogen gas formed is 758.0 mmHg - 24.5 mmHg = 733.5 mmHg.
