a student collects hydrogen gas over water in a graduated cylinder. if the student measures that the total pressure inside the graduated cylinder is 0.949 atm and the experiment was performed at 25oc, what is the pressure of hydrogen gas? enter your answer numerically in units of atm.

Answers

Answer 1

The pressure of hydrogen gas is 0.9177 atm. The result is obtained by using the Dalton's law of partial pressures.

What is Dalton's law of partial pressures?

The Dalton's law of partial pressures states that the total pressure of a mixture of gases equals the amount of the partial pressures of the component gases. It can be expressed as

p = p₁ + p₂ + p₃ + ... + pₙ

Where

p = total pressure of a mixture of gasesp₁, p₂, p₃, ... = partial pressures of gases

Collected hydrogen gas over water in a graduated cylinder. The total pressure inside the graduated cylinder is 0.949 atm at the temperature of 25°C.

What is the pressure of hydrogen gas?

At the temperature of 25°C, the vapor pressure of water is 0.0313 atm.

If the total pressure of the mixture of gases is 0.949 atm, the pressure of hydrogen gas is

p = p vapor of water + p hydrogen

0.949 = 0.0313 + p hydrogen

p hydrogen = 0.949 - 0.0313

p hydrogen = 0.9177 atm

Hence, the pressure of hydrogen gas is 0.9177 atm.

What does experimental error entail and how was it calculated?

A value's experimental error is the discrepancy between the value that was measured and the actual value. Or, to put it another way, it is the error or inaccuracies that prevent us from seeing a measurement that is 100 percent accurate.

Every measurement has some degree of experimental error, which occurs frequently. The experimental error is determined as follows in this instance.

The formula to determine percent error is percent error = [(approximate value - exact value) / exact value] 100.

Explanation:

Exp takes into account the observed value, in this case 1.4 cm, while theo takes into account the theoretical value, in this case 1.2 cm. As a result, the final number is: Error = (1.4 - 1.2)/1.4 = 0.1428571429 * 100 = 14.3%.
