The uncertainty principle is one of the most famous (and probably misunderstood) ideas in physics. It tells us that there is a fuzziness in nature, a fundamental limit to what we can know about the behaviour of quantum particles and, therefore, the smallest scales of nature. Of these scales, the most we can hope for is to calculate probabilities for where things are and how they will behave. Unlike Isaac Newton's clockwork universe, where everything follows clear-cut laws on how to move and prediction is easy if you know the starting conditions, the uncertainty principle enshrines a level of fuzziness into quantum theory.

Suppose there is a gaseous mixture of nitrogen and oxygen. If the total pressure of the mixture is 480 mmHg, and the partial pre
Rudiy27

Answer:

Partial pressure of oxygen = 190 mmHg

Explanation:

From the question;

Mixture contains only nitrogen and oxygen

Total pressure of the mixture = 480 mmHg

Partial pressure of nitrogen = 290 mmHg

Dalton's law states that the pressure of a system is as a result of the sum of the partial pressures of the individual components of the mixture. This means that in this mixture;

Pressure of mixture = Partial Pressure of Nitrogen + Partial Pressure of Oxygen

480 = 290 + Partial pressure of oxygen

Partial pressure of oxygen = 480 - 290

Partial pressure of oxygen = 190 mmHg
