Dalton's law
The pressure exerted by one gas in a mixture
The pressure exerted by one gas in a mixture (apex)
Yes. That is True. Dalton's Law is: that pressure exerted by a mixture of gases is the sum of the pressures exerted independently by each gas in the mixture. Reference: Human Anatomy and Physiology Marieb and Hoehn
To find the total pressure exerted by the gas mixture, you can sum the partial pressures of all the gases. Therefore, the total pressure is 112 kPa (oxygen) + 101 kPa (hydrogen) + 65 kPa (nitrogen) = 278 kPa. Thus, the total pressure exerted by the gas mixture is 278 kPa.
Since the gases behave ideally, the partial pressure of each gas in the mixture is directly proportional to the number of moles of that gas present. Here, since equal weights of methane and hydrogen are mixed, the number of moles of each gas is also equal. Therefore, the fraction of the total pressure exerted by hydrogen is 1/2 or 50%.

The total pressure of a gas mixture is the sum of the individual pressures.
The partial pressure of oxygen is a measure of the pressure exerted by oxygen in a mixture of gases. In atmospheric air at sea level, the partial pressure of oxygen is around 160 mmHg. The partial pressure of oxygen can also be calculated using the equation: partial pressure of oxygen = total pressure of gas mixture * mole fraction of oxygen gas in the mixture.
