The density of citronellal, a mosquito repellant,Is 1.45 g.L - 1 at 365 $\omicron $ C and 50.0 kPa.What is the molar mass of citronellal?

Question

Quizplus · Accepted Answer

The molar mass of citronellal can be calculated using the ideal gas law equation, $PV = nRT$, where $P$ is the pressure, $V$ is the volume, $n$ is the number of moles, $R$ is the ideal gas constant, and $T$ is the temperature in Kelvin. Given the density, we can find the molar mass by rearranging the equation to $M = \frac{dRT}{P}$, where $M$ is the molar mass, $d$ is the density, $R$ is the gas constant (8.314 J/mol·K), $T$ is the temperature in Kelvin (365 + 273 = 638 K), and $P$ is the pressure in Pa (50.0 kPa = 50000 Pa). Plugging in the values, we find that the molar mass closely matches the value given in option B.
