Dalton's Law of Partial Pressure Calculator: Here is one of the greatest tools for quickly calculating the partial pressure of any gas. It provides precise outcomes in a short amount of time. For all of these laws, you can learn the law of partial pressures, which includes ideal gas law, Dalton's law, Henry's law, and partial pressure formulas. Learn how to calculate partial pressure using simple steps and get answers to queries about it.
Pressure is the force that is applied orthogonally over a surface. If you fill a container with a perfect gas mixture (molecules that don't interact), the gases will disperse and take up all of the available space. Partial pressure is the pressure exerted by one component of this mixture.
According to Dalton's law: A gas mixture's total pressure on a container's walls is equal to the sum of the partial pressures of each individual gas. An equation can also be used to illustrate it Total Pressure = p1 + p2 +... + pn. The partial pressures of each gaseous component are represented by p1, p2, and so on, up to pn. partial pressure = total pressure * mole fraction
The mole fraction is the ratio of the selected gas's moles to the total gas mixture's moles. It demonstrates that a component's partial pressure is proportional to its mole fraction.
According to the ideal gas law equation: p * V = n * R * T
Use the following formula (derived from the one above) to compute the partial pressure of one component of a gas mixture: pi = (ni * R * T) / v
According to Henry's law, The partial pressure of a gas above a liquid is proportional to the amount of gas dissolved in the liquid. Henry's constant is the proportionality coefficient. When we have a concentration of the solute, we employ Henry's law method 1. Pressure = KH1 x concentration
When the mole fraction of the solute is known, Method 2 is utilised. Pressure = KH2 x mole fraction, Where, Henry's law constant (litre x atm/mol) is KH1. Henry's law constant in the atm is KH2.
Element | Henry's law constant [litre*atm/mol] | Henry's law constant [atm] |
---|---|---|
O2 | 769.23 | 4.259*104 |
H2 | 1282.05 | 7.099*104 |
Co2 | 29.41 | 0.163*104 |
N2 | 1639.34 | 9.077*104 |
He | 2702.7 | 14.97*104 |
Ne | 2222.22 | 12.3*104 |
Ar | 714.28 | 3.955*104 |
CO | 1052.63 | 5.828*104 |

The following is the procedure how to use the partial pressure calculator
1. What is the procedure for calculating partial pressure?
Ptotal=P1+P2+... +Pn. + Pn. The total pressure of a mixture of gases can be described as the sum of the individual gas pressures: The partial pressure of a single gas is equal to the total pressure multiplied by the gas's mole fraction.
2. With partial pressure, how do you find K?
Subtract the partial pressure of H2 from the overall pressure to get the partial pressure for H2O. Then, in terms of activities, write K (equilibrium constant expression). Solids and pure liquids are not taken into account.
3. How do you find partial pressure from moles?
The ideal gas equation may be adjusted to show that the pressure of a sample of gas is directly proportional to the number of moles of the gas present if volume and temperature are kept constant: P=n(RTV)=n×const.
