Dalton's Law
Explicación
## Step 1The problem is asking us to identify the principle that states that the total pressure exerted by a mixture of gases is equal to the sum of the partial pressures of each individual gas in the mixture. This principle is known as Dalton's Law of Partial Pressures.## Step 2Let's briefly discuss the other laws mentioned in the options:- Charles's Law states that the volume of a given mass of a gas is directly proportional to its temperature on an absolute scale if pressure and the amount of gas remain unchanged.- Boyle's Law states that the pressure of a given amount of gas held at constant temperature is inversely proportional to the volume.- Graham's Law states that the rate of diffusion of a gas is inversely proportional to the square root of its molar mass.## Step 3From the above explanations, it is clear that only Dalton's Law is related to the total pressure of a gas mixture being the sum of the partial pressures of the gases.
