The density of a gas can be calculated using the ideal gas law:PV = nRTwhere P is the pressure, V is the volume, n is the number of moles, R is the ideal gas constant, and T is the temperature.We can rearrange this equation to solve for the density:density = (n/V) * molar masswhere molar mass is the mass of one mole of the gas.In this problem, we are given the density of ethane at 25°C and 1.13 atm pressure. We can use the ideal gas law to calculate the number of moles of ethane in a given volume:n/V = P/RTn = (P * V)/RTWe can then use the molar mass of ethane to calculate the density:density = (n/V) * molar massdensity = [(P * V)/RT] * molar massWe can plug in the given values to solve for the density:density = [(1.13 atm * 1 L)/(0.0821 L*atm/mol*K * 298 K)] * 30.1 g/moldensity = 1.39 g/LTherefore, the correct answer is A) 1.39 g/L.
