Determing an element

  1. Dec 18, 2011 #1
    1. The problem statement, all variables and given/known data
    At 1000 deg C and 10 torr, the densit of a certain element in the gaseous state is 2.55×10^-3 g/L. The element is:

    2. Relevant equations

    3. The attempt at a solution
    So, i took the the density equation, that of which is derived from the ideal gas law, and rearranged to solve for the molar mass, but, unfortunately, it did not suceed. What am I to do to solve this problem?

    What molar mass did you get?

    I got 21 g/mol--which is the answer. Sorry, i was looking at the wrong answer
