Daltons law of partial pressures calculator- Online calculators

Dalton's law – a joint term for two different laws, formulated by John Dalton, which are mutually complementary:
- partial pressure law
- partial volume law

Dalton's law (also called Dalton's law of partial pressures) states that in a mixture of non-reacting gases, the total pressure exerted is equal to the sum of the partial pressures of the individual gases. This empirical law was observed by John Dalton in 1801 and published in 1802 and is related to the ideal gas laws.

If gas 'i' is a ideal gas, then according to the Clapeyron equation, in this volume it exerts a pressure called partial pressure, given by the formula:

$$ p_{i} = \frac{n_{i}}{V}RT $$
The sum of the partial pressures of gases i = 1...k is:

$$ \sum_{i=1}^{k} p_{i} = \sum_{i=1}^{k} \frac{n_{i}}{V}RT = \frac{n}{V}RT = p $$

where:
$ n_i $– number of moles of individual components,
$ V $- molar volume,
$ R $- universal gas constant,
$ T $- temperature,
