To calculate the partial pressure of the blue gas in a mixture, you would typically use Dalton's Law of Partial Pressures, which states that the total pressure of a mixture of gases is equal to the sum of the partial pressures of each individual gas.
If the total pressure of the mixture is given as 1.30 atm, you will also need to know the mole fraction or the ratio of the partial pressures of the gases in the mixture to find the specific partial pressure of the blue gas.
Without additional information about the mole fractions or the specific contributions of other gases in the mixture, I can't calculate the partial pressure of the blue gas accurately.
However, if you assume a certain ratio, for example, consider that the blue gas makes up a certain percentage of the total pressure, you could find the partial pressure using the formula:
\[ P_{\text{blue gas}} = \text{Mole fraction of blue gas} \times P_{\text{total}} \]
If you provide the necessary ratio or contribution of the blue gas to the total pressure, I can help you calculate the partial pressure specifically!
