Use the molar volume of a gas at STP to determine the volume (in L) occupied by 10.5g of neon at STP.

  • chem - ,

    1 mol of Ne has a mass of 20.18 g and occupies a volume of 22.4 L at STP.

  • chem - ,

    im not sure how to approach the problem i got 11.6 L

  • chem - ,

    That's right.
    10.5 g x (1 mol/20.18 g) = 0.5208 mols.
    0.5208 mols x (22.4 L/mol) = 11.65 L which to 3 places is 11.6 L so you got right.

    thank you!
