    The average molar mass of the mixture is 37.184 g/mole

    Explanation:

    Density of mixture = 1.66 g/L

    1 mole of mixture contains 22.4 L by volume

    Molar Mass of mixture = 1.66g/L * 22.4 L/1 mole = 37.184 g/mole

    Answer: The average molar mass of the mixture is 37.184g/mol

    Explanation: Density of Argon and Neon at STP = 1.66 g/L

    1 mole of a mixture always contains 22.4L at STP.

    Therefore, Molar Mass of Argon and Neon =

    1.66g/L * 22.4 L/1 mol = 37.184 g/mol
