question

A gas sample is known to be a mixture of ethane and butane. A bulb having a $230.0 \mathrm{~cm}^3$ capacity is filled with the gas to a pressure of $97.5 \times 10^3 \mathrm{~Pa}$ at 23.1∘C23.1^{\circ} \mathrm{C}. If the mass of the gas in the bulb is $0.3554 \mathrm{~g}$, what is the mole percent of butane in the mixture?

A gas sample is known to be a mixture of ethane and butane. A bulb having a $230.0 \mathrm{~cm}^3$ capacity is filled with the gas to a pressure of $97.5 \times 10^3 \mathrm{~Pa}$ at 23.1^(∘)C. If the mass of the gas in the bulb is $0.3554 \mathrm{~g}$, what is the mole percent of butane in the mixture?
