∙ 16y agoDalton's Law of Partial Pressures can be combined with the Ideal Gas Law to derive a simple equation that is useful in relating the partial pressure of a single component of a gas mixture to the total pressure, and to the mole fraction of the gas in the mixture. Dalton's Law states that the sum of the partial pressures of the individual gases of a gas mixture is equal to the total pressure of the mixture: Ptotal = P1 + P2 + ... + Pn The Ideal Gas Law relates the pressure (P), volume (V), temperature in Kelvin (T), and the number of moles of gas (n). PV = nRT rearranging to give, P = (nRT)/V Because both of these laws are indepedent of the identity of the gas, expressions can be written for a single component gas as well as a mixture of gases when at constant volume and temperature: Ptotal = (ntotalRT)/V and P1 = (n1RT)/V Division of the two expressions results in: P1/Ptotal = n1/ntotal The quantity n1/ntotal is the mole fraction of gas component 1, X1, and substitution into the previous equation yields the expression: P1 = PtotalX1 This final expression allows the partial pressure of a single component of a gas mixture to be related to the total pressure of the mixture and the mole fraction of the component. Applying the same reasoning to any of the mixture components yields similar relationships of any of the component gases. As a result, it is possible to determine the composition of a mixture of gases from the partial pressures of the gases in the mixture, or to pressures from the mole fraction.

What does law of conversion of energy say?
The law of conservation of energy states that "energy can not be created (made) or destroyed (made gone)"
What does Avogadro's law say about gas at STP?
1 mole of gas at STP occupies 22.4 liters.
What does it mean when people say water has an unevenly distributed charge?
The hydrogens in water carry a partial positive charge, and the oxygen carries a partial negative charge. This is because of the differences in electronegativity, and the fact that the geometry of the water molecule is bent.
The only reactants in a reaction were Zn and HCI. What does the law of conservation of matter say about the products?
The product will contain only Zn, H, and CI. -Apex
What would Proust say about the composition of all carbon dioxide molecules?
He would insist that all Carbon Dioxide molecules have the same composition, by his Law of Constant Composition.
What does Dalton's Law of Partial Pressures say?
The total pressure of a gas mixture is the sum of the individual pressures.
What benefits do we have from John Dalton's discovery?
Daltons experiments with gases also led him to form two more chemical laws, the Law of Partial Pressures (behaviour of gaseous mixtures and dissolving of gases into liquids) and the Law of Multiple Proportions (ratios and gas composition). It is needless to say that without Dalton's work and consequent theories, Chemistry as we know it today may not exist.
What did daltons theory say about protons and electrons?
Nothing,Dolton did not know about Protons,neutrons and electrons
How do you say partial in German?
English: "partial" means in German "teilweise".
What does nitrogen have to do with diving?
when you go diving, you take a pressurized tank of air, air consists of about 79% Nitrogen and 21% Oxygen, at normal pressure (atmospheric pressuer) the partial pressure of Nitrogen is 0.79 Bar and Oxygen 0.21 Bar which is safe. Under high pressures (say 5 Bar which is at a depth of about 40 metres) the partial pressure of each gas increases Nitrogen (0.79x5=3.95Bar) which causes the lungs to absorb the nitrogen at a higher rate which influences the nervous system causing Narcosis (As if you're Drunk) The reason why you can't take a tank of oxygen instead of air is that oxygen becomes toxic at higher partial pressures
What is the prefix of the word partial?
You could add the prefix im- to it to make the word impartial.
