a glass jar containing .27 mol of Nitrogen with a leaky lid is heated from room temperature 22 celcis to 150 celcis. How many moles of Nitrogen remain? How many gtams?

  • chemistry - ,

    Note the correct spelling of celsius.

    I assume this is at room pressure.
    I would use PV = nRT, assume 1 atm for P, substitute and solve for volume in L.
    Then Use PV = nRT again, this time with volume first calculated, keep P at 1 atm and solve for n.
    You can convert to g by g = mols x molar mass.
